> We are running Asterisk 13.4 PJSIP in a production environment and get random crashes. Everything seemed to be working fine for a couple of days and we now get crashes more and more.
> I have also noticed that crashes happens even though no calls are made, so I don't think it has anything to do with the dialplan. I've really tested everything in a test machine before moving my dialplan to PJSIP. Most of the phones use direct media, so the load on asterisk is low.
> I get no errors when doing asterisk -cvvvvvvvvvvvvvv.
> [Edit by Rusty - For reference here I'm extracting from your debug log the last lines before the crash.]
