New subject: [Serusers] XJAB problems...

9 Jul 2003

All,

    I've been playing with jabber module and having problems someone
had  mentioned here earlier: first, the number of ser processes
increases constantly . This is due to the fact that XJAB threads seem to
be dying (or so waitpid() code thinks in jabber.c), and keeps spawning
more threads. The proble is that ser threads are still around when that
happens, contributing to a number of processes.

    Second, and most troubling, is that jabber module doesn't even try
to connect to jabber server (conformed by running ngrep and tcpdump on a
jabber box, which runs on a separate box). This may or may not be due to
the error described above (any chance that jabber threads that are
supposed to connect are not around anymore?). I even tried disabling TCP
and recompiling (commented -DUSE_TCP in Makefile.def)

    The rest of ser functionality is fine. I can log in tp the server
easily, mysql gets updated acorrdingly, etc.

    The setup: ser-0.8.11pre29 on Linux 2.4.9 (host name piias12),
compiled with gcc 3.2.2. Jabber runs on a server "sait661".

    The jusers looks like this:

mysql>  select * from jusers;
+------+--------+------------+----------------------+------+
| juid | jab_id | jab_passwd | sip_id               | type |
+------+--------+------------+----------------------+------+
|    1 | igorb  | ***        | igorb(a)piias12.ms.com |    0 |
+------+--------+------------+----------------------+------+
1 row in set (0.00 sec)
