[asterisk-users] Run-away Asterisk

[Yuan LIU]

After testing some AGI's, I noticed several extra Asterisk processes.  They 
are not zombies, but can't be killed by safe_asterisk.  Nor will they die 
when CLI issues stop now.  Then I read that each AGI spawns a separate 
Asterisk process.  But all my AGI calls have apparently completed 
successfully.  So there should be no reason for them to hang there.

Several questions:

1) Under what conditions will an AGI hang a process? (My test scripts are 
pretty simple, almost directly derived from agi-test.agi.)

2) How to detect run-away processes under 2.4 kernels?  In this kernel, each 
thread clusters process space and it's very difficult to distinguish them 
without killing the main process.

3) Any practical way to detect them from inside Asterisk - e.g., do some 
check after each AGI call?  All my AGISTATUS reports success.  I could use 
System() but isn't that cumbersome?

Thank you.
