asterisk users - Dec 2007 - CAPI didn't get a frame | avoiding initial deadlock | multiple instances of Asterisk

Hi guys,

First of all, I know that this server must be upgraded asap, I'm just
wondering if anyone of you has already faced this problem and , if so, would
the upgrade solve my problems...

CAPI version 0.6
Asterisk 1.2.5
AGI scripts are being used

Main problems:

-Dropped Calls

- ps aux | grep asterisk shows that asterisk (that is started with
safe_asterisk) is generating multiple instances of asterisk by it's self.

This may be caused by AGI scripts  http://bugs.digium.com/view.php?id=8086?

I definitely must go through CAPI 1.0 and asterisk 1.2.25, but would be
interesting to learn from this problem before upgrading, that's why I'm
posting on the list.

Could it be possible that the multiple instances of Asterisk that are
started due to the bug ( http://bugs.digium.com/view.php?id=8086, solved in
asterisk 1.2.13) are causing all the troubles, making this multiple
instances try to access same asterisk channel (leading us to Avoiding
deadlock messages) ?

I mean applying the patch might solve the problems instead off all system
upgrade?
