Hi Andrew,

If you can catch one of these events, and get a traceback of the stack, I will take a look. This is not happening to most users, so it must be some specific combination of things on your machine. I have reports of high volume faxing running for extended periods from some users.

Regards,
Steve

Why would you expect a bunch of fax modems to work any better than
spandsp? If spandsp doesn't work reliably your system is very likely
broken.



I've had spandsp crash out on some kind of floating point error about a half dozen times over about 250 faxes.... When it crashes it takes Asterisk down with it. These systems are SuperMicro Xeon server-class systems, no overclocking, RAM was tested overnight with memtest86, no-nonsense, nothing funny type machines. SpanDSP and Asterisk were both compiled with the same compiler without any oddball optimizations (just whatever's in the default makefiles).


It's a bitch to try and reconstruct, but it's the only reason I'm not using spandsp in production; when I was using spandsp I had it on a completely separate machine on the local LAN to avoid the spandsp crashes from taking the voice part down.
