| Jun 14, 2014 at 2:37 | comment | added | Aquarius Power | If my workaround about pids doesnt work I will think on a way to ask that question properly :). This question is mainly about counting wraps. I am still open to other solutions tho. My answer is "narrowed" (doesnt most ppl use ubuntu?) to ubuntu, but I would like to see another that could workaround random pids distribuition even if I cant test it. | |

Especially the sleep 1 part, it just sounds hack-ish to me that a script will need to drift in and out of sleep every second just to check if pids have wrapped or not. Essentially, I'm agreeing with @MarkPlotnick that you should have a follow-up question asking how can you remove these PID files after the processes have stopped running... | |
| Jun 13, 2014 at 20:00 | comment | added | Aquarius Power | the pids are unique only for running processes, new process can have a pid of a died proccess; the script relies on a file that contains the pid information, but before such file being removed there is a delay of 10 minutes, meanwhile a new process got the same pid of a dead process and so the file was not removed; the tip by @MarkPlotnick made me think on adding the full command line to that file and so "pid vs cmd" would mostly be a unique enough combination, anyway I was able to create a script that count the wraps what is what I was interested in knowing :) | |
