[KLUG Members] Apache hung up at 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....

kernel-smp-2.2.19-7.0.8
glibc-2.2-12
apache-1.3.14-3
imap-devel-4.7c2-12
php 4.0.6 (compiled as a module)

 './configure' '--with-apxs' '--with-ldap' '--with-pgsql' '--with-informix'
'--enable-sysvsem' '--enable-sysvshm' '--with-imap' '--enable-sockets'
'--with-gd' '--with-ttf' '--with-jpeg' '--with-png' '--enable-ftp'
'--disable-mysql'

Hardware: Dual Pentium III (Katmai) 498.699MHz Netfinity 5000

Looked around and haven't seen anything that appears obviously relevent to this
problem.  Anyone heard of any such problems with the mentioned
apache/php/kernel.  I'm entirely sure it is not IMP itself as this is the EXACT
same set of PHP files as before the upgrade.
