One of our Perfsonar nodes has been acting funky over the past week or so.  Our monitoring shows HTTP/HTTPS going up and down at random times during the day, I’ve confirmed it is actually going down as I cannot access perfsonar-hartford.cen.ct.gov during those times.  It can be anywhere from a few minutes and has lasted up to 30 minutes.  I’ve rebooted multiple times, power cycled it, yum is all up to date, etc.  Tests and results seem fine, it just seems to be HTTP/HTTPS access.  I’ve looked through some of the httpd logs but nothing is jumping out at me. 

 

Based on what I can see on your system from the outside, Apache is up and pScheduler is up and answering queries that don’t have anything to do with the schedule.  The latter leads me to suspect that something in the database is jammed up, and I’d like to get a handle on what that is.

 

If you’d be so kind as to run “pscheduler diags” as root and send me the results off-list, I’ll have an initial look at what’s going on.  Alternately, if you want to jump on video sometime today, drop me a line and we can troubleshoot it live.
