Yes, this is the warning I told about in other mail.

The same occurs (kamailio takes 50-99% CPU) in case there is a problem
with MySQL and Kamailio cannot write into it.
It seems that when kamailio process must wait for something (TCP
connection, MysQL access) it consumes CPU resources (waiting).

Makes sense since no TCP listener is available :(

It will not solve the issue. The only it does it setting the TCP
connection duration for the registration expires time. It has nothing
to do with failed TCP connections.
