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

Free -m is as follows 

[root at localhost cron]# free -m
             total       used       free     shared    buffers     cached
Mem:          2025       1974         51          0         43       1806

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 .
