Hey Alex,
thanks for your prompt insights! This info will have saved me quite some
mistakes ;)
thx!

If you want to rate-limit traffic below the throughout
thresholds of the
children, look at the pipelimit module. It would obviate the need for
manual htable statekeeping.

Workers process SIP messages, which means both requests and replies. So,
you can't use request-oriented tracking to make that decision.
The answers to your question are basically:
1. Keep your call processing as fast and light as possible.
2. Use async methods.
Async methods only help so much, due to the strict timing tolerances of
SIP, and real-time, delay-sensitive communication in general. The
fundamental answer is basically #1--incur as little delay as possible.

Gents,
assuming we don't use async methods (I know, it's against fashion),
eventually you'll end up in having some bottlenecks in your config...
Now thanks to a lot of children you can easily work around this, a
maximum of 32 children gives you already quite something, and if you use
the dispatcher, you can ramp that up to quite some capacity. ;)
Now, there are moments where still limits are passed, so what would be
the best way to keep your system healthy?
I was thinking in the direction of using a hashtable value or $var to
keep track of the children in use and e.g. if 31 children are used, refuse
to process the 32th request (assuming 32 children are setup). Would this
be a valid strategy? Or am I overthinking?
Grtz,
Davy
