[Serusers] Voicemail config producing errors and zombies

[Jeff Harrington]

All,
	I've been working on voicemail for a while, and haven't made much 
progress.  In looking through the archives I've come up with a few example 
configs.  My latest attempt gives me a number of errors.  I was hoping some 
of the experts could help out with where I'm going wrong.  I'm still in a 
test mode, so there are only 2 people registering.  When I try to start 
ser, I get the below errors, and a large number of Zombie processes:

Sep 10 15:46:52 enforcer ser[30812]: connect_db(): Too many connections
Sep 10 15:46:52 enforcer ser[30812]: db_init(): Error while trying to 
connect da
tabase
Sep 10 15:46:52 enforcer ser[30812]: ERROR; vm_init_child: could not init 
db mys
ql://ser:heslo@localhost/ser
Sep 10 15:46:52 enforcer ser[30812]: init_mod_child(): Error while 
initializing
module voicemail
Sep 10 15:46:52 enforcer ser[30812]: init_children failed

My config looks like this:

         # we record-route all messages -- to make sure that

        };

#rewriting the flag with UsrLoc
if (is_user_in ("Request-URI","voicemail")) {
         setflag(4);
};

  #mark transaction for voicemail (routing block 2)
         if (!lookup("location")){
                 route(2);
                 break;
                 }

#forward to voicemail now
rewritehostport ("199.109.32.11:5090");
t_relay_to_udp("199.109.32.11","5090");
}
#if forwarding downstream did not succeed, try voicemail running on port 5090

         revert_uri();
         rewritehostport ("199.109.32.11:5090");
         append_branch();
         t_relay_to_udp("199.109.32.11","5090");
}

Any advice as to what I can try would be appreciated.

Thanks,
