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

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

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 .

1.4.18
Centos 4.6

I can reproduce Asterisk crash by doing pages to SIP phones on two
different servers.
While running top I can see free memory dropping with each successive page
until safe_asterisk restarts my system.
I dont have valgrind installed or dont optimize enabled etc... so I cant
be much help with backtraces but the crash is definitely reproduced with
paging.
I only have 4 phones in my page group so I page successively about 60
times to reproduce the crash.
