perfSONAR User Q&A and Other Discussion

[Marian Babik <>]

Hi All,
noticed an exception in the pscheduler logs, so I wonder if someone has seen 
this already:
Sep 11 15:25:36 perfsonar-lt safe_run/ticker ERROR    Restarting
Sep 11 15:25:36 perfsonar-lt safe_run/ticker ERROR    Program threw an 
exception after 0:00:00.002590

Despite the errors, pscheduler works fine as there are new results being 
posted to the MA. 

# lsof | grep pscheduler | wc -l 
22890

Thanks,
Marian
