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; } }
