FS#364 - Crash in TCP Read on Kamailio 4.0.1
User who did this - Vitaliy Aleksandrov (Vitaliy)
----------
I have one setup which crashed two time during the last week. It crashed when tried to
accept TLS connection, but bt looks similar to the one in this report.
Details:
- Kamailio works as a gateway between WSS and TCP transports.
- System version is 4.1.0-dev9 (x86_64/linux) 576dce-dirty.
Compressed core file is in the attachment.
Backtrace:
