asterisk users - May 2011 - asterisk's zombie processes

I'm monitoring Asterisk with Nagios. Nagios constantly alerts because of too
many zombie processes. I eventually had to disable the notification for the
alert but why does Asterisk create so many zombie processes, I've see more
than 30 at times and it generally stays in the 20s... just seems unusual and
wondering if it's harmful, thanks in advance.

Are you sure it's Asterisk creating the zombie processes, not the 
check_sip pinger in Nagios?

Nagios is extremely bad with high throughput and concurrency, and 
check_sip is a wrapper around 'sipsak', which means it takes the full 
Timer T1 * 64 to time out if the Asterisk server is truly not available 
(about ~30-32 sec).

Asterisk creates threads, not processes.

Trace back from the PPID of the zombies to see who created them

Hello,

I am the lead developer of Enswitch. Enswitch comes with commercial 
support as standard, so if you suspect there's a problem with Enswitch 
we (or our partners if you've bought a system through them) would be 
delighted to take a look as part of normal support. If you're unsure of 
how to do this, please drop me an email off-list letting me know your 
name and what company you work for and I can give you details of how to 
contact support.
