Error: broken pipe!

#1
Hi,

Recently there was an incident in our DC which caused our server to shutdown for a while.

After recovering the server, we found that we now get heaps of errors in the LiteSpeed server logs:

connection to [/tmp/lshttpd/lsphp5.sock.750] on request #1, confirmed, 1, associated process: 30605, running: 1, error: Broken pipe!

The symptom is that APC crashes every minute, thus driving the response time to the roof. Some responses are being dropped completely.

We run 4.0.12/4.0.13 with PHP 5.2.12 + APC (3.1.3p1) with LSAPI 5.2 (but we also tried 5.3 and 4.10). We have not changed any settings before and after the DC incident.

Some basic hdd test did not reveal any disk related issues. Any thoughts on what could have caused this?

Thanks!
