Matt Jordan commented on ASTERISK-21244:
----------------------------------------

You're crashing in {{libsrtp}}:

{noformat}
#0  0x00007f8e6490632e in rdb_add_index () from /usr/lib/asterisk/modules/res_srtp.so
#0  0x00007f8e6490632e in rdb_add_index () from /usr/lib/asterisk/modules/res_srtp.so
No symbol table info available.
#1  0x00007f8e6490240f in srtp_unprotect_rtcp () from /usr/lib/asterisk/modules/res_srtp.so
No symbol table info available.
{noformat}

{{srtp_unprotected_rtcp}} is actually a function call in {{libsrtp}}. Historically, when we've seen crashes in {{libsrtp}}, they've been extremely difficult to reproduce.

# Did something change in this library on your system? What version of it are you running?
# If you disable SRTP, do you continue to have issues?
# What phone model is calling in that causes the crash? What is the relevant portion of the dialplan?
# Can you provide a pcap with RTP/RTCP/SIP leading up to the crash?

> Installed asterisk from source and it worked perfectly for days, then today it suddenly stopped working. I can start the Asterisk service and as soon as a call is attempted it crashes / segfaults and does a core dump if run with that option to do a core dump.
> Only message in /var/log/... is in the syslog:
> Mar 13 21:49:23 ip-10-212-91-161 kernel: [ 6471.432979] asterisk[24621] general protection ip:{redacted} sp:{redaced} error:0 in res_srtp.so[7f7551ce3000+13000]
