perfSONAR User Q&A and Other Discussion

[Trey Dockendorf <>]

Thought I'd add that I'm seeing this on two of my perfsonar boxes too.  So far the regular testing seems to show as "Not Running" more frequently on the host performing bandwidth tests than the host performing latency tests.

Below are last entries in /var/log/perfsonar/regular_testing.log.1 before I manually restarted the regular testing daemon.

2014/12/11 00:29:14 (2299) DEBUG> Master.pm:198 perfSONAR_PS::RegularTesting::Master::handle_child_exit - Received SIGCHLD for PID: 2304

2014/12/11 00:29:14 (2299) DEBUG> Master.pm:198 perfSONAR_PS::RegularTesting::Master::handle_child_exit - Received SIGCHLD for PID: 2305

2014/12/11 00:29:14 (2299) DEBUG> Master.pm:198 perfSONAR_PS::RegularTesting::Master::handle_child_exit - Received SIGCHLD for PID: 2303

2014/12/11 00:29:14 (2299) DEBUG> Master.pm:258 perfSONAR_PS::RegularTesting::Master::handle_exit - Process 'perfSONAR_PS Regular Testing' exiting

The global registration service seems to get hung on both systems equally.  I see no obvious errors in /var/log/perfsonar/ls_registration_daemon.log.  I do notice that there are a few entries that mention "Duplicate checksum".

Hello all,

 

I am dealing with an issue in which regular testing on our perfsonar box (3.4.2) stops sporadically, and the box appears to lose its global registration – global registration changes from “yes” to “no”.  I have not seen anything in the logs that would indicate why this is happening, but I am a novice with this tool and I may be missing something.  Restarting the services seems to resolve the issue temporarily, but it always crops back up.
