Some more information:
mysql_options(ptr->con, MYSQL_OPT_RECONNECT,(char*)&my_auto_reconnect)
is internally implemented as:
case MYSQL_OPT_RECONNECT:
mysql->reconnect= *(my_bool *) arg;
break;
and that code is already present in 2.0:
if (!mysql_real_connect(ptr->con, id->host, id->username, id->password,
id->database, id->port, 0, 0)) {
LOG(L_ERR, "new_connection: %s\n", mysql_error(ptr->con));
mysql_close(ptr->con);
goto err;
}
/* Enable reconnection explicitly */
ptr->con->reconnect = 1;
This is the old way of enabling automatic reconnects in mysql but it
does the same.

MySQL 5.0.X automatically times out its sockets after a hardcoded period
of time. Unless you have configured the socket to auto reconnect (see
http://www.ideasip.com/support/utils/my_con.c.SER2 ), after a little
while, the socket will just time out and you will have to restart SER in
order to connect to the database (it will throw errors).
I thought that issue was resolved. Can you check the tracker ticket and
verify that it is scheduled for ser 2.0 release?
It is fixed in a different way in 2.1, but it was not backported to 2.0
(see
http://lists.iptel.org/pipermail/serdev/2007-June/010460.html).
Jan, have you forgotten to backport it or is there some other reason?
(patch for 2.0 attached)
Andrei
