Hi Yury,
it looks like you some multiple issues, overlapping here. The traps you
sent here have nothing to do with the auto-scaling, but with a blocking
TCP connect for SIP - most of the procs get blocked into a sync TCP connect.

Hi Bogdan,
I've applied the patch (had to find where to apply it manually for
3.2.8 downloaded from Web page, line 1568 instead of 1652) and
restarted the server with only about 300-350 SIP devices and
immediately got into same issue. I'm attaching two GDB dumps made
within several minutes from each other. Autoscale was now OFF, please
see my previous message as currently for some reason I'm experiencing
lockups even when it's off :(
Best regards,
Yury.

Hi Yuri,
Could you give this patch a try? it should fix the blocking you
experience (it should apply on 3.2 too).

Hi Yury,
Thanks for the details info here - let me do a review of some
code and run some tests, as at this point I have a good idea on
the direction to dig into.
I will update here.

Hi Bogdan,
Yes, I'm listening on all types of sockets including UDP, TCP
and TLS on the outside public interface and then forward traffic
into internal LAN via UDP only.
Previously it was getting stuck quite easily, now I had to wait
for a while before this actually happened. I've routed part of
my customers to this server to obtain this result so I will have
to do that again.
As soon as I see one of the processes stuck I'll dot the trap
command and send you all the details including processes load,
ps output and so on.
For now I had to switch autoscaling off and just create many
listeners. Do I understand correctly that I need to restart
OpenSIPS in order to apply autoscaling profiles and
reload-routes is not sufficient?
Also, do I need separate UDP profiles for public and private
interfaces? And do I need to apply autoscaling profile just to a
socket or I need to specify udp or tcp_workers with autoscaler too?
Thanks and best regards,
Yury.

Hi Yury,
Thanks for the info. I see that the stuck process (24) is an
auto-scalled one (based on its id). Do you have SIP traffic
from UDP to TCP or doing some HEP capturing for SIP ? I saw
a recent similar report where a UDP auto-scalled worked got
stuck when trying to do some communication with the TCP
main/manager process (in order to handle a TCP operation).
BTW, any chance to do a "opensips-cli -x trap" when you have
that stuck process, just to see where is it stuck? and is it
hard to reproduce? as I may ask you to extract some
information from the running process....
