[SR-Users] load testing ims_charging

[Kelvin Chua]

i am trying to load test the ims_charging module and notice some issues

whenever i send test calls one by one, it's perfect. but when i use sipp
and generate a bunch of calls, i would get this intermittently

CRITICAL: ims_charging [ro_timer.c:122]: insert_ro_timer(): Trying to
insert a bogus ro tl=0x7f207e91c2d0 tl->next=0x7f207e8b57b8
tl->prev=0x7f207e97c398

if i continue to hammer the server, it would end up failing all calls. When
this issue happens, Ro_CCR will not return any value and will also not
trigger the async route, looks like it just sits there frozen. during this
time, sip client will receive a 408.

also notice cdp complaining of latency usually around 1 second, using
packet capture i am sure diameter server is responding properly. i think
there is a choke point somewhere. i tried playing around with
async_workers, no improvement.

any pointers?
