Re: Parallel::ForkManager and possible memory leak

in reply to Parallel::ForkManager and possible memory leak

Does the server not hang if you don't run the script? Are there logs that you can sift through to see what's happening when the server hangs and if it's consistent in some way?

When I say hangs it is not accessible. Cannot login, scp, sftp, anything. It is pingable but that is all. I have print statements in the code, I didn't post them, I just wanted to be sure the code portion is correct. This hanging issue has only happened once I started the fork process. If I remove the Parallel::ForkManager and just let the script run one server after the other, then it runs fine, but it takes well over 5 minutes to complete. I have a snippet of logging from yesterday where the server became unusable. I have print statements that say when the program starts, when the child processes have ended. When we hit the timeout condition it appears that the server had issues. 02/16/15 10:34:03 Program SendRemote_PullMetrics Started Mon Feb 16 10:36:28 2015: Waiting For All Child To Finish Mon Feb 16 10:36:34 2015: All processes finished. 02/16/15 10:36:44 Program SendRemote_PullAPIMetrics Completed 02/16/15 10:39:05 Program SendRemote_PullMetrics Started Mon Feb 16 10:41:39 2015: Waiting For All Child To Finish Mon Feb 16 10:41:45 2015: All processes finished. 02/16/15 10:41:58 Program SendRemote_PullAPIMetrics Completed 02/16/15 10:44:07 Program SendRemote_PullMetrics Started TimeOut Over 3 Minutes to Complete All Servers, Continuing... Never got a complete message and then the Server became unusable.	[reply]
