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

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

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 .

I was unable to come to work yesterday and so I just now got to read the
last five notes on this issue.

The problem is that there is no simple solution for these core dumps you
are experiencing. I want very badly to fix this but unfortunately, As I
said a few notes ago, this issue is not solvable through static analysis of
the code. Since I have not been able to reproduce the issue myself, it
means that someone, anyone, who also experiences these same types of core
dumps should run valgrind in order to detect where invalid memory accesses
are so that we can fix this once and for all.
