[SR-Users] replay of tls delayed by 30 secs.

[José Seabra]

Hi,

Kamailio has some configuration options that logs a msg to the syslog when
some config script action takes more time that is expected, the  options
are:

   - latency_limit_action=500
   - https://www.kamailio.org/wiki/cookbooks/4.1.x/core#latency_limit_action
   - latency_limit_db=500
   - https://www.kamailio.org/wiki/cookbooks/4.1.x/core#latency_limit_db
   - latency_log=2
   - https://www.kamailio.org/wiki/cookbooks/4.1.x/core#latency_log

The issue could also be related with the TCP write queue, maybe you have
set low values on the following parameters:

   - tcp_conn_wq_max
      - https://www.kamailio.org/wiki/cookbooks/4.1.x/core#tcp_conn_wq_max
   - tcp_wq_max
      - https://www.kamailio.org/wiki/cookbooks/4.1.x/core#tcp_wq_max

Other hint is to look for the OS  send Queue, the package could be delayed
because the other end is not reading it fast enough:

   - netstat -altp

it also will be important try to isolate the issue in terms of SIP, the
transaction delayed(UPDATE) is always the same in all situation that the
issue occurs?

Hope that the information above helped you.

Regards
José
