[OpenSIPS-Users] Dialog default timeout issue

[Bogdan-Andrei Iancu]

Hi Chen-Che,

Those logs are really relevant to your dialog expire problem. What those 
logs say is that some timer routines (like ds-pinger or tm-timer) took 
very long to execute ( like 2 or 4 seconds) and this leads to delays in 
the execution of the following timer routines (the timer process gets 
delayed). This is a limitation of 1.x OpenSIPS versions, where timers 
are executed in sequential order in a single process (and if one gets 
slow, it will affect the other too).

The ides is to address the timer routines reported as being slow. The 
tm-timer can be moved into a separate process :

For the dispatcher pinger - how many destinations do you have in the 
list ? also, do you have some TCP destinations in there ?
