Summary: Monitor/tm counter overflowing/corrupting in 1.4

Initial Comment:
Default 1.4.0 install on a AMD64 FreeBSD install.

External box used to generate large number of invites with pjsip-perf...


Implemented as such:
pjsip-perf --count=50000  --method=INVITE sip:0 at kam.box.ip:5060 


Identified in kamctl monitor with output of such after 50K calls run on the default config with 32M of shm.. lots of "tm:new_t: out of mem" message show up and the pjsip-perf exits after ~ 32K calls are generated and some calls timeout longer then 60 seconds..  Monitor displays as such:


Server:: Kamailio (1.4.0-notls (x86_64/freebsd))
Now:: Wed Sep 17 13:31:55 2008
Up since:: Wed Sep 17 13:25:21 2008
Up time:: 394 [sec]

Transaction Statistics: 
tm:UAS_transactions = 31476
tm:UAC_transactions = 0
tm:inuse_transactions = 4294967294



This appears to happen only after the inuse_transactions is back to 0 after the calls stopped.

Message:
To understand: the inuse_transactions is incremented properly under the
load test, then comes back to 0 an go over flow? Looks like going negative
and printed unsigned...
