I seem to recall a memory leak in pbx_spool being fixed a few days ago.

Hi,

After only 4 days I have 107472352 bytes in 46007 allocations in file 
'pbx_spool.c'

And top shows me that asterisk is using 153m virtual memory and 141 res 
memory... Only completely stopping asterisk and starting again will free 
up the memory.

What could be causing this?  I did read something about call files and 
variables in the past, but that was a long time ago. I do have to 
process .call files but not that many...

Could there be a memory leak in pbx_spool.c, how can I help troubleshoot 
that?

Thanks
Walter.

Hi,

It may have been fixed, but then it doesn't run for more than a few seconds
:-)

Tried to update to CVS from just now (2005-10-16 +0800), and my asterisk now
dies a few seconds after starting up with:
Ouch ... error while writing audio data: (Segmentation fault)

Even a completely clean install did not help. Apparently without the addons it
seems to run longer, but my sip and iax peers are running off mysql, so
can't really do without.

What I did notice during the time it was running (before it segfaults) and I did
a show memory summary pbx_spool.c did not show up at all.

Isn't that weird?

Anyway to troubleshoot this segfault? Normally I would see it right after a
module is loaded, but it now happens anywhere from 2 to 10 seconds after
asterisk loads.

Any help appreciated.

Walter.
