The crash was not related to websocket at all, but to
usage of uac_reg_lookup() when you don't set reg_db_url parameter for uac module.
So, my question is why are you using uac_reg_lookup()? Because it is useless if you dont
set reg_db_url and you don't have records in uacreg database table. This function is
related to the feature of kamailio to send register to another sip server with a
contact address pointing back to kamailio.
To summarize on another words, the crash happened because the kamailio.cfg didn't
have set the expected uac module parameters by uac_reg_lookup() function.
I was
using uac_reg_lookup() without reg_db_url because it appeared to be performing the same
job as a pair of uac_restore_from() and uac_restore_to(). I have made corresponding fixes
in my configuration file.
However, the previously mentioned issue of abrupt disconnection persists. I get this in
the logfiles:
Apr 9 17:22:23 elx3 /usr/sbin/kamailio[8573]: WARNING: websocket [ws_frame.c:868]:
ws_keepalive(): forcibly closing connection
At the same time, I get the following sequence of javascript messages in the Firefox
browser:

The code in uf.js retries the connection, but eventually it times out again.
