The outage this afternoon was caused by a failed attempt to install ossn, an open source social network program onto our web site. Things seemed to work until I turned cache on then it went to a blank screen. I gave up and went to bed (about 6am).
This afternoon I discovered our website wasn’t responding, complaining of mysql descriptors, apparently ossn got stuck in some sort of loop and ate them all up. I’ve removed the program from the server until I can determine what is wrong.
