[asterisk-dev] Core Dump from res_musiconhold.c Crash

[Steve Totaro]

Maybe someone can help me with this.  I am running 1.2.7.1 and my 
Asterisk system crashed after issuing a reload with approximately 100 
concurrent sales calls (many in queue listening to music on hold).  We 
have modified a few sections of the source (mostly AMI) so have been 
reluctant to upgrade to 1.2.12.1.  I know there were alot of bug fixes 
in queues (which we use extensively) between 1.2.7 and 1.2.8.

My question is, is/was this a known bug fixed in a later version of 
asterisk?  If not, do I open a bug on Mantis?  I plan on upgrading 
Asterisk on Friday morning and applying my patches which hopefully goes 
smoothly.  Is there any reason not to go all the way to 1.2.12.1?  This 
is a heavy use (6,000 calls a day) call center system.

The reload seems to have set total_files to zero and caused a divide by 
zero error?  I am not a dev guy but looking at the code, that is all I 
could come up with.
