what is the number of children you set in your configuration file? Try
with children=16 or 32. If you use t_relay(), openser should sends back
a 100 trying once the request is forwarded, in order to stop the
retransmission of the request from caller. You can do it stateless via
sl_send_reply() just a beginning of your script if you have
time-consuming operations.
I used the default children=4, but tried with 16 and 32 and it still
retransmits.
I use t_relay.
The actual thing I observe is that openser starts to process the first
calls just fine and at a point it just freezes and does not give
neither 100 trying nor anything else. Then in 1-3 seconds it starts
replying again, and after 2-3 seconds it gets clogged again.
I wolud appreciate any other ideas. Like is there some way to maybe
increase the memory openser is using?
Anyway, OpenSER does not answer the calls, it just routes them. Check to
see if asterisk is able to manage all the traffic you send to it - it is
the box which answers the call.
Actually just to test the openser i sent non-existing numbers not to
load the asterisk too much. I just want to get the trying an/or error
messages from openser and that is where it times out often.
In my scenario i authenticate the invites, and the initial 401 which
challenges the invite to be retransmited with user info is also
timeouting at similar loads and times, so no asterisk there.
