Re: [SR-Users] crash when sending reply

Kamailio 5.5 crashed when sending reply (bt full below). Before the crash there had been several mysql related error messages ("Lost connection to MySQL server during query" and "Too many connections") in syslog when async worker tried to insert accounting data. So perhaps this core dump has something to do with that. -- Juha Reading symbols from /usr/bin/sip-proxy...done.
