Hung on semop

[Adam Tauno Williams]

I have IMP 2.2.1 on our interal web server.  Prior to a recent upgrade of the
systsem software (OS, apache, etc...) this product was 100% stable.  Since the
upgrade it (IMP) has been getting hung every few hours performing a semop.  All
other server functions and web pages continue normally, but IMP stops working
for all users.  Using strace and ipcs I can see an httpd sitting at semop on
IMP's semaphore id.  Doing a "/etc/rc.d/init.d/httpd stop" stops all put one
httpd,  and a strace -p {pid{ of that http shows it sitting in semop.  I have
recompiled PHP just to make sure it was all happy,  but the problem seems to
still exists.  Has anyone seen this before?

Currently running....
