Summary:                    memory leak
Description: 
hi we are using asterisk 1.4.18 , zaptel-1.4.8 and libpri 1.4.3 with 4 e1
card on ibm x3200 server and 90 active calls running on asterisk cli and
after some hours of dialing , swap memory starts getting used and asterisk
gives core dump .

Asterisk is running with safe_asterisk.

vmstat ouput is as follows 

[root at localhost cron]# vmstat
procs -----------memory---------- ---swap-- -----io---- --system--
-----cpu------
 r  b   swpd   free   buff  cache   si   so    bi    bo   in   cs us sy id
wa st
 1  0    568  57308  44708 1848488    0    0    10   119 1293  509  2  2
95  0  0

Free -m is as follows 

[root at localhost cron]# free -m
             total       used       free     shared    buffers     cached
Mem:          2025       1974         51          0         43       1806
-/+ buffers/cache:        124       1901
Swap:         1983          0       1983


OPERATING SYSTEM is centos 5 and kernel version is [root at localhost cron]#
uname -a
Linux localhost.localdomain 2.6.18-8.el5 http://bugs.digium.com/view.php?id=1
SMP Thu Mar 15 19:57:35 EDT
2007 i686 i686 i386 GNU/Linux

Cannot do valgrind test as it put heavy load on the server and its a
production server .

RAM On the server is 2GB .

Only Asterisk application is running on that .

While I appreciate the amount of data you're providing, it's not especially
helpful. When diagnosing a memory leak, what we need is the output of
several "memory show allocations" and "memory show summary" on the same
running process. The idea is that we can see a change in the number of
allocations over time and possibly pinpoint where the memory leak(s) is.
Outputting a single memory summary for a process is not helpful since it
gives no reference point for the memory allocations later in the process.

Also, given the crashes experienced, I have a feeling that this is more
than just a memory leak and that there's some sort of corruption happening
here. There are a few similar issues on the tracker right now, and it would
be nice if we could figure out what the common elements are in the setups.
