Understanding that text lacks tone, this a rather offputting comment for a
mailing list intended to help users. I appreciate your time and feedback,
there's no need to be insulting. Perhaps you could stop assuming what my
preoccupations and scope of vision are and concentrate on the problem and
the solution? The question now is why increasing buffers made any
difference at all.

You suggested to "Monitor your receive queue scrupulously at a very high
timing resolution". How do I do this?

You propose there is a pathological issue and the increased buffer size is
masking it. How do I determine what that issue is?

I've asked repeatedly about children, shared memory, process
memory, timer_partitions, etc. but the only answers have been "try more".
I've been trying more and less of these things two weeks and changing the
buffers was the only thing that appeared to have any immediate impact. How
do I know when enough is enough versus too much?

Note, there have been no memory-related log messages. The 16-thread servers
have 48GB RAM and the 8-thread servers have 16GB. I'm happy to give all
that to OpenSIPS once I know the right way to carve it up.

Should I even be using 2.4?
