I am running 1.2.34 (also tried on 1.2.32) and whenever I launch an AGI, I
get the "avoided deadlock" message below.
*CLI> == Spawn extension (CONTEXT3, 6080, 8) exited non-zero on

This is purely a test box and it has two phones on it and one AGI, so there
is no issue with utilization. Everything I read about deadlocks says this
is a bad thing. I know it says "avoided deadlock", but this happens
every
single time I use an AGI, even with nothing else happening on the box. Is
this really something I should be concerned about, or is it no big deal? I
am worried that if I put this into production with 200+ phones, it will
cause Asterisk to die.

A deadlock? In 1.2?

In 1.2? Really? :)Well, that was helpful. As a fellow 1.2 Luddite, I have boxes running xxx simultaneous channels, all running xx AGIs per call with no problems. First off, unless you have good reasons, you should move to a newer version just to improve your chances of getting meaningful support on this list. Do you get this deadlock message when you launch any AGI, for example, agi-test.agi? -- Thanks in advance, ------------------------------------------------------------------------- Steve Edwards sedwards at sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000
