Apache Error Issues?

[65fastback2+2]

I keep getting backend login issues...reviewing the error reporting, its showing:

 

 

The Apache error log is simply recording a script timeout for that page.

Looking at the running process list, there are instances of that script which have been running (without apparently doing much, as most have used 0 seconds of CPU time) for 15+ minutes.

Attaching to one of those processes with strace, it's waiting on a file lock for a session file.

root@host [~]# strace -p16344

The other PHP processes are also attempting to lock that same session file.

 

Anyone have any ideas?
