Hi Di-Shi,
My guess is (as your module probably does external communication via network)
that some function in your module does block in a I/O op while trying to
communication with an external entity.
Based on your description I do not see how opensips it self can block (like
the sl_send_reply() function).
So, to debug something like that, simply "block" all opensips processes and
then attach to them with gdb in order to take a backtrace (while opensips still
running) - this will indicate where the processes blocked.
Attach to the SIP worker processes - they are blocking ; the fifo process
works ok as it does not handle SIP traffic, so it does no block .
Regards,
Bogdan

Hi All,
We are testing our module that gets routing info from outside of OpenSIPS.
OpenSIPS routes calls based on these info. If our module returns empty routing
info for a call to OpenSIPS, OpenSIPS uses sl_send_reply to fail the call.
In heavy load, our module returns empty routing info to OpenSIPS quickly.
Soon, all OpenSIPS SIP listen threads stick forever. OpenSIPS does not crash
and it can still accept fifo command. We did not see any error message in
OpenSIPS log. We also did not see any memory related message. If we make our
module to return the empty routing info slower, OpenSIPS SIP listen threads do
not stick.
Would you please tell me what issue it may be and which part I should dig
more deep?
Thanks,
