[asterisk-users] Asterisk stops responding

[Carlos Chavez]

     I am having a problem with an Asterisk 1.6.2.15 server that runs a small
call center with Queuemetrics.  In the past month we've had this problem 3
times.  

     The problem is that Asterisk simply stops responding.  No calls in or out
and you cannot even get to the CLI.  The process seems to be running but there
is simple no activity.  All I see in the log files is:

[Jan 14 16:30:46] WARNING[20747] pbx.c: Failed to create new channel thread
[Jan 14 16:30:46] WARNING[20747] chan_sip.c: Failed to start PBX :(
[Jan 14 16:30:47] WARNING[20745] pbx.c: Failed to create new channel thread
[Jan 14 16:30:47] WARNING[20745] chan_dahdi.c: Unable to start PBX on DAHDI/29-1

     After restarting Asterisk everything is back to normal.  The time between
the first failure and the second was almost a month, between the second and
third a few days.  

     We use CentOS 5.5 on a Dell 905 server with 8gb of ram.  The first time
it happened we were using Asterisk 1.6.2.14 so we upgraded to 1.6.2.15 to try
and avoid the problem but no luck.  Any recommendations?
