Summary:                    high chan_sip use count (mem leak)
Description: 
Hello, i have a average of 66 active SIP channels (33 active calls)
and asterisk use 374MB(VIRT) 301MB(RES) after 1 week, 5 days uptime.
Suspicious is chan_sip Use Count:

asterisk -rx'module show like chan_sip.so'
Module                         Description                             
Use Count
chan_sip.so                    Session Initiation Protocol (SIP)       
1540

But "sip show channels" only show the 66 aktiv SIP channels (the ACK's and
INVITE's)
So where are the 1540 chan_sip uses from that probably cause the memory
leak?

A function like "module show linke chan_sip.so uses" perhaps can show
what's going wrong.

I'd say a backtrace of Asterisk running along with 'core show locks' from
the Asterisk console would be a start. Also, this seems to be posted
against 1.4.34, and 1.4.35 is out and 1.4.36-rc1 (which is going to become
1.4.36 later today) is available. I'd suggest testing of those versions
would be beneficial as well.
