Jon Christopherson updated ASTERISK-20394:
------------------------------------------

    Attachment: asterisk-backtrace.txt

I am still getting crashes on 1.8.16.0, still pointing to memory corruption. I tried running with valgrind, but the performance hit made it unusable. I did attach what little output i got to this report earlier.Here is the latest core dump from today when asterisk got busy.


asterisk[1848]: segfault at 7f8f0000001a ip 00000030a1279115 sp 00007f90eac9b720 error 4 in libc-2.12.so[30a1200000+189000]
