perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

Copying the perfsonar-user list in case others have insights. I do recall a 
thread about the usage shooting up last year. We hypothesized at the time a 
web crawler or similar was hitting the server and confusing it, but we could 
never confirm. It's made more difficult by the fact that it's unclear who the 
maintainer of the NPAD source is these days. Are you running version 3.3.2 of 
the toolkit? I haven't heard reports in awhile but that doesn't mean people 
have stopped seeing it (just stopped emailing about it). It's also possible 
(though probably unlikely) that if you are running an old version of the 
toolkit that some update fixed it.

Thanks,
Andy
