perfSONAR User Q&A and Other Discussion

[Lixin Liu <>]

Hi,

One of my latency hosts stopped reporting test results starting sometime 
early today. 
I see the load on the process

        perfSONAR Regular Testing: Measurement Archive: 
esmond_latency_localhost

is always at 100% and regulartesting.log continues showing errors like this:

2016/06/18 21:48:23 (2656) WARN> regulartesting.pl:103 main::__ANON__ - 
Warned: IPC::DirQueue: killed stale lockfile:

I hope someone could help me to figure out what needs to be done to resolve 
this
problem. The hostname of the machine is lat-usask.westgrid.ca.

Thanks,
