Badalian Vyacheslav commented on ASTERISK-24333:
------------------------------------------------

Sorry. We have 1-3 Crash in WS mode every day. 
Glibc say for random errors like:

asterisk[3328]: segfault at d9c36b47930 ip 0000003be3c47e3c sp 00007ffd16531410 error 4 in libc-2.12.so[3be3c00000+18a000]
asterisk[47139] general protection ip:3be3c47e3c sp:7f360d06d410 error:0 in libc-2.12.so[3be3c00000+18a000]
Also have errors for double free.
WS mode also use SRTP?
