[Serusers] SUBSCRIBE timeout again

[Andrey Kouprianov]

Hi,

I am having the same problem with SUBSCRIBEs again.... SER just keeps
on sending me
back timeouts for them... The problem persists only for any other
presentity except myself.
SUBSCRIBE timeouts happen most of the times, however, it's only
sometimes, that they get through.

Here's a part of ser.cfg responsible for SUBSCRIBE and NOTIFY:

. . . . . .

 if(method=="SUBSCRIBE") {
     if (!www_authorize("sip.interlab.ait.ac.th", "subscriber")) {
         log(1, "Authentication for SUBSCRIBE");
         www_challenge("sip.interlab.ait.ac.th", "0");
         break;
     };

     if(!lookup("location") ) {
         log(1, "No registered user found for SUBSCRIBE request");
         sl_send_reply("404", "Not Found");
         break;
      };
 };

 if(method=="NOTIFY") {
      if (!www_authorize("sip.interlab.ait.ac.th", "subscriber")) {
         log(1, "Authentication for SUBSCRIBE");
         www_challenge("sip.interlab.ait.ac.th", "0");
         break;
     };

      if (!lookup("location")) {
         log(1, "No registered user found for NOTIFY request");
         sl_send_reply("404", "Not Found");
         break;
      };
 };

 if( !t_relay() ) {
    sl_reply_error();
 };

 . . . . . . . .


Here are the traces:

. . . . . .

And so it goes, until SER replies with Timeout.

There are no error messages in the log.

Can you tell me what is wrong???
