[Asterisk-Users] Serious memory leak in asterisk (manager)

[Roy Sigurd Karlsbakk]

hi all

after getting some (or - a lot) of messages from nagios, claiming 
asterisk
to be down, I found this out...

astping xxx times repeatedly, and the manager fails to start. this 
little
script was used for testing. below, I've pasted the output from 'ps 
axfv' before and after the DoS, showing asterisk having allocated ~2GB 
RAM.

#!/usr/bin/perl -w
use strict;
my $i = 0;
while (1) {
         $i++;
         system("astping pbx");
         if ($? != 0) {
                 printf("asterisk crashed after %d astpings\n", $i);
                 exit;
         }
}
