Our servers all runs at 99% CPU (ten of them), and at times, the server crashes with the log file showing:
(1) ++++ failed to get SockIO obj for: myserver.com
(2) [com.danga.MemCached.MemCachedClient] (TP-Processor146 ++++ attempting to read from closed socket
(3) 2010-03-23 15:23:11,552 119562968 ERROR [com.danga.MemCached.SockIOPool] (MaintThread +++ removing potentially hung connection from busy pool ... socket in pool for 41947ms
Any idea what could be causing this?
BTW, I have 10 servers all of them having memcached running and configured. memchached process does not show to take much of cpu or memory
We are using memcached version 1.2.2 and com.danga.MemCached client version 2.0.1
