Li Weijia and Director Liu did not go to the computer room with Li Lin, but stayed in Director Liu's office. However, Director Liu had already greeted the people guarding the computer room, and when Li Lin came to the computer room according to the route that Director Liu said, there were already people waiting for him.

"It's Mr. Li, Director Liu told me on the phone just now, let me lead you in." A young man who didn't seem to have grown his hair yet, as soon as he saw Li Lin coming, he took the initiative to come up.

"It seems that this is also a relational household, and it looks like he is not yet 20 years old." Li Lin guessed in his heart, didn't dwell on this, and said politely: "Then it's troublesome." ”

The young man led Li Lin into the computer room, and suddenly the roar of the machine reached his ears, and the temperature dropped suddenly. In order to prevent the server from being damaged by high temperature, the air conditioners in the computer room are specially made, and the power is several times higher than that of ordinary air conditioners, so basically the temperature of the computer room is very low. It is said that a certain foreign company is a computer room built near a snow-capped mountain, and tens of thousands of servers are saved in a year, and the electricity cost saved is astronomical.

When the server is usually stored in the computer room, there is no such thing as a screen, keyboard and mouse, it is just a machine, surrounded by various slots, and it looks like a CD player that has been magnified several times. However, the computer room is generally equipped with one or two sets of peripherals, so that when someone comes to view the server, they can temporarily plug in the screen, keyboard and mouse to operate the server.

The young man took Li Lin to the server of the file system, and then plugged in the screen, keyboard, and mouse before turning around and leaving.

Li Lin looked at the code of the file system and quickly discovered the root cause of the system crash, but he was not 100% sure whether he had completely solved it. The reason for the system crash is very simple, it is memory leakage, but this kind of problem is very troublesome to find, which is why Secretary Yang and Director Liu, including his second uncle, have not been able to solve it after finding so many people. Because it is not an ordinary code logic problem, but a code vulnerability caused by a lack of deep understanding of the code execution process. The reason for the memory leak is that the storage space in the computer is limited, but the root cause is the low level of the programmer. In the process of running the program, it will continue to generate temporary data, which can also be called garbage data, if it is not cleared in time, the final result will inevitably be that the storage space is occupied and the program crashes. This is just like the public trash can at the staircase in the high-rise community, if it is not cleaned up by the property people every day, the residents will only throw it away, and sooner or later the entire staircase will be occupied, and the building will be completely wasted.

Li Lin came over this time to see if the memory of the system was normal, and if the memory occupation was normal, it could be regarded as a complete solution. Because the code that leaked memory is not necessarily in one place, it may be in multiple places, and Li Lin only found one, so before the results came out, he was not sure that he had not missed it.

Under normal circumstances, the memory footprint of a program, if you draw a graph according to time, should be zigzag to be considered normal. In other words, it should rise to a certain extent, and it will come down, and it will always be some distance from the limit. Just like the public trash cans just mentioned, every time they are almost full, there will be a property staff to clear them.

If a memory leak occurs, the memory usage of the program will generally be a slow upward trend until it reaches the limit, and then the system will die. In other words, the garbage in the public trash can is thrown away by the residents faster than the property staff, so the final result must be a mountain of garbage until the staircase is filled.

Memory leaks are like a chronic poison that starts to feel normal, and only when the memory is completely occupied, the toxicity will completely erupt, and once it does, it will completely destroy the host.

Previously, Director Liu and Secretary Yang said that the program was fine when it was first started, but after a day or two, it crashed directly, which is a symptom of memory leakage.

Li Lin carefully observed for a while and found that the current state of the system is normal, and the memory occupation is very stable, which means that there is no other memory leakage, and the problem is completely solved.

When he came out of the computer room, Li Lin looked at the time, it was almost 5 o'clock. Although Director Liu had a very bad attitude towards him before, since the other party took the initiative to say that he wanted to treat him, it could be regarded as an apology in disguise, and for the sake of his second uncle, Li Lin naturally would not refute the face of others.

Li Lin, Li Weijia and Director Liu chatted together for a while, and at 6 o'clock, they left the information and communication office to go to the hotel. Li Lin is still in the same car as his second uncle, while Director Liu is driving another car, leading the way in front.

On the way to the hotel, Li Weijia praised Li Lin from head to toe, which made Li Lin very embarrassed, so he could only modestly agree. It is not difficult for those who will meet, but it will not be difficult for those who are difficult, it is a big problem for Li Weijia, Secretary Yang and Director Liu, but for Li Lin, it is indeed just a gesture.

When I arrived at the hotel, Secretary Yang was already waiting at the door of the hotel, and Li Lin barely spoke much during this meal, but Li Weijia, Secretary Yang and Director Liu kept praising each other back and forth.

Of course, he occasionally praised Li Lin, but he only smiled modestly and did not answer. After all, the other three are all their elders, and when the adults speak, the juniors still try to intervene as little as possible.

The meal went very smoothly, Li Lin didn't speak much, and used all his strength to eat. I have to say that the food in this restaurant chosen by Secretary Yang is quite delicious.

This time, the three of them drank a lot of alcohol, so they didn't drive when they left, they all took a taxi back, and the car had to wait until the next day to pick it up.

Li Lin had no other place to go in the county, so he naturally followed his second uncle home. Early the next morning, Li Weijia took Li Lin to pick up the car and sent Li Lin directly to the city's train station.

"Second uncle, go back. I'm a big boy, I can't lose it. Li Lin saw that the second uncle had to wait for him to get in the car before leaving, and said helplessly. He found that since he helped Secretary Yang and Director Liu solve the problem, the second uncle's attitude towards him has changed slightly, and it should be said that he has become more attentive.

"Okay, don't rush the second uncle, it's all sent here, are you afraid to wait for a while." Li Wei's family doesn't seem to be leaving early.

There were less than 20 minutes before it was time to get on the bus, Li Lin simply gave up, and let the second uncle accompany him. It wasn't until Li Lin entered the ticket gate that Li Weijia left the train station and roared towards the county seat.

And Li Lin once again stepped on the train to the north of the capital county

Li Lin got on the train, put his luggage away, and sat in his seat. Each row on the train is divided into three or two, with three seats on one side and two people on the other, and Li Lin is on the outermost part of the three-seater side.

However, at this time, the two positions next to Li Lin and the three positions opposite were no one, Li Lin looked at the people coming and going next to him, and closed his eyes with lack of interest. Ever since he became a telekinesis, he likes to close his eyes when he has nothing to do, starting out because he wants to experience the magic of perception, but now it has gradually evolved into a habit.

"Handsome guy, please let me go."

As soon as Li Lin closed his eyes, he heard someone talking, and a powerful perception told him that this person was talking to him. It was obvious that this was the passenger sitting next to him, and Li Lin didn't open his eyes, but he turned sideways very cooperatively and let the other party pass.

But what made Li Lin strange was that this person stood next to him and didn't move, and even Li Lin felt that this person's body trembled inexplicably, but before he could open his eyes, a scream sounded in his ears.

"It's you!"
