Hi Everyone,

 

This has happened before, seemingly only to our OWAMP instances. The symptoms are:

 

·         The toolkit web page never stops “loading”

·         High CPU

·         Regulartesting.log displays “Problem storing results: Error writing metadata: 500 Timeout”

·         No response to Nagios checks from another host

·         But scheduled tests appear to be running

 

The last case began Saturday May 14 at ~22:25, and ended today at 12:39.  I have searched all the logs I can think of and have not found any clues as to why it started, or why it ended.

 

Any guidance would be appreciated.

 

Thanks!
