Hi Andrei,

From what I have seen in the code this is pretty useless (no offence).

The ping in this particular instance is only executed JUST before a real query is to be issued. i.e. if a query is not used in Kamailio for a couple of hours - the ping is actually never sent...........

what I have noticed is that when the connection is torn down by the firewall, the ping actually hangs (reconnect fails), etc

So, we NEED a proper ping (keepalive) functionality :D

Cheers
Jason

Doesn't modparam("db_mysql", "ping_interval", 15)  work?
