Every couple of days one of the servers locks up, with all the processes stuck in a lock wait. It looks like the process that created the lock crashed, all the others get stuck and that server needs a bullet.

Steve,

I haven't had any problems running 5.3.3 on Debian, but then you
obviously have additional packages (i.e. I don't have APC running).

Is there anything in your server logs? No matter what you have in yours
scripts, the process shouldn't crash.

Without knowing the cause of the crash, it's impossible to determine if
an upgrade will be of any help.
