of all presence server processes when presence server is not responding to
any new requests. looks like several processes are in futexlock.h if that
tells something.
It is a sign of deadlock.
I looked quickly over the code and it seems that in 4.0 there are some
error cases when an acquired lock is not released.
Didn't have the time to make a fix, but if someone has time before I can
get back to it, look in pua module, in send_subscribe.c,
send_subscribe(...) function.
If the module is not in PUA_DB_ONLY, there is a lock acquired:
lock_get(&HashT->p_records[hash_code].lock);
And in the following lines of code I could spot some 'goto error'
without a lock_release(). To get a patch, I would need more time to spot
all the cases, which I don't have for the moment. Maybe someone else can
jump in, otherwise I will look over it when I get the first chance.
Cheers,
Daniel
this is with kamailio 4.0.
