[OpenSIPS-Users] What does exactally mean lots of warnings about timer_ticker in the log (OpenSIPS 2.1)?

[Rodrigo Pimenta Carvalho]

Ok Eric.


Thank you very much.

I will analyze my OpenSIPS configuration and try to discover what action is causing the block situation.


Best regards.

I was just speaking with bogdan, apparently i am wrong.  he said:

"no, there is no way to do that, as right now any process (SIP worker) can execute (if free) the timer jobs, and the timer_partitions in TM has nothing to do with that change (in how timer jobs are executed)"

So ... i guess you need to prevent any type of blocking operations ...

Ok Eric.

Thank you. I will try  this and see what will be the result.

I believe this has been refactored under 2.X as a result ofthe async work.  I think the new settings are "timer partitions" here is the tm documentation discussing the timer partition setting: http://www.opensips.org/html/docs/modules/2.1.x/tm.html#id294483
tm Module - OpenSIPS<http://www.opensips.org/html/docs/modules/2.1.x/tm.html#id294483>
www.opensips.org<http://www.opensips.org>
TM module enables stateful processing of SIP transactions. The main use of stateful logic, which is costly in terms of memory and CPU, is some services inherently ...

Hi Eric Tamme.


I have just searched about Timer in the module docs, but I didn't find any thing about how to manager Timers in OpenSIPS, as you commented.

Do you know what part of the documentation tells about "dedicated timer processes"?


BTW, my project is embedded.


Any hint will be very helpful!


Thanks a lot!

Many things share the same timer, dialog expiration cleanup, userlocation cleanup, nathelper pings etc.  If one of the processes that is triggered by a timer route blocks for some period of time - aka a hung db query, it will cause the timer to "drift" and you will get logs indicating that a process that should have takeng X amount of time actually took Y amount of time - this is due to the blocking operation.

I would suggest that you use dedicated timer processes for as many things as you can - dialog, tm etc. see the module docs for how to do this.

Hi.

The log of my OpenSIPS began to present thousands of warnings similar to:



"WARNING:core:timer_ticker: timer task <nh-timer> already schedualed for 93991120 ms (now 248157560 ms), it may ove rlap.."


What does exactly means it?

Some discussions from the past said something about increasing the number in the global variable "children".


Should I change the number for children?  Before trying it i would like to hear something about, just to know better what I'm going to do.


Any hint will be very helpful!


Thanks a lot.
