Thank you!

I will compare your configuration with mine.

Best regards.

Assunto: Re: [OpenSIPS-Users] Continuous "WARNING:core:timer_ticker: timer task <tm-timer> already scheduled" messages in log

So i made two changes to my config:

  1.  per Bogdan, changed my timer_partitions to: modparam("tm", "timer_partitions", 4)
  2.  I had previously used some settings found in a number of configuration examples in my transaction module. After a little research, I commented them out. Still doing some research into whether these new (default) values may trigger other problems.  My new config is as so (snippet):

#### Transaction Module
loadmodule "tm.so"
# modparam("tm", "fr_timeout", 5)
# modparam("tm", "fr_inv_timeout", 30)
# modparam("tm", "restart_fr_on_each_reply", 0)
# modparam("tm", "onreply_avp_mode", 1)
modparam("tm", "timer_partitions", 4)

Since making these changes and restarting, the messages have gone away.

Hello Steve,

What OpenSIPS tells you is that you the TM timer routine (which gets executed once per second) takes longer than 1 second (as execution). Probably you have retransmissions or many failure routes to be executed.
You can increase the level of parallelism in TM timer via the timer_partition parameter:

Try to set it to 4.
