we have recently moved to our newly configured ASA5520 from PIX, everything is correct and working fine, except that randomly ASA reboots itself without any message in the syslog. i can't seems to trace anything that what's causing it to happen..
ASA 5520 version 7.2(1)
even i doubt that there is any other factor causing it to reboot except something in software
has anyone every experienced it before, i tried googling but no specific answer.
