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. -------------- next part -------------- An HTML attachment was scrubbed...

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).

Trace back from the PPID of the zombies to see who created them -- Thanks in advance, ------------------------------------------------------------------------- Steve Edwards sedwards at sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000

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.
