About Error FileNotFoundError: [Errno 2] No such file or directory: '/proc/12825/stat' the some suggest

[IT-IvDragon]

when I was useing the function process_iter discover a not myself can catch the error。
For errors like FileNotFoundError: [Errno 2] No such file or directory: '/proc/xxx/stat'。
I searched for problems in lssues , but found that the latest version didn't fix them. Through the source code found that this function only catch the NoSuchProcess exception，and this error I think is a problem with pids functino，pids from /proc dir fetch a unusua path，lead to open the path /proc/xxx/stat raised an exception，so we can do try/catch the FileNotFoundError error at the open file location。

I encountered the same problem.
[Errno 2] No such file or directory: '/proc/1535931/stat'
After investigating,
I found that there are some anomalies with the /proc/1535931 directory. It doesn't contain the stat file, which causes the read error.

Since it runs on a server and I don't have permission to delete the anomalous process directory, I had to use a simple but effective method: skipping this PID.

Successfully run after modification.

you can in the function process_iter add try finally ，skip the pid when happen error。

[giampaolo]

Are you saying file /proc/1535931/stat does not exist but directory /proc/1535931 exists? If that's the case, what's the content of directory /proc/1535931?

[IT-IvDragon]

yes ，I met the problem just not exist stat file， the other file/directory in directory /proc/1535931 is exist，I think is Linux system because of some special circumstances not create the stat Or the /proc/1535931 directory wasn't deleted

[giampaolo]

Can you do ls -la /proc/1535931 and paste the output?

[IT-IvDragon]

I tried ls ，but cannot find the progress id ，just the /proc/1535931 dir

[giampaolo]

So the /proc/1535931 directory is empty?

[IT-IvDragon]

not empty, there are some files, but no stat file

[giampaolo]

OK, paste those files. Paste the output of ls -la /proc/1535931 command.
