Summary: Stuck Transactions/Memory Leak with B2B top hiding

Initial Comment:
I am experiencing a memory leak when using the B2B modules with the internal "top hiding" scenario. It appears to be related to struck/un-freed transactions, as the opensips mi will report many thousands of inuse_transactions when the reality is only a handful. An example is we currently show 15000+ inuse_transactions while only a handful of calls are actually in progress. These transactions appear to build up over time.

Opensips information:
version: opensips 1.8.0-notls (x86_64/linux)
flags: STATS: Off, USE_IPV6, USE_TCP, DISABLE_NAGLE, USE_MCAST, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, FAST_LOCK-ADAPTIVE_WAIT
ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535
poll method support: poll, epoll_lt, epoll_et, sigio_rt, select.

main.c compiled on 12:24:36 Aug  3 2012 with gcc 4.4.6

I currently have the memdump option enabled and am waiting for another buildup of transactions to gather the memdump information. I can supply access to the dump and the opensips configuration file via email.

Message:
Ryan,

I will try to see if I can reproduce this. You can simple topo hiding
scenario, with successful calls, nothing special, right ?

Regards,
Bogdan
