I have a serious problem with my corporate firewall, witch is an ASA 5520, fv 8.3, with 8 +1 interfaces.
It suddenly started to crash every 10/20 minutes and rebooting alone.
First of all I checked system resources witch are in a very low usage state.
I also checked interfaces errors, but nothing strange come out o from error counters analisys.
I tried disabling logging and all the service policy rules configured, but nothing changed.
Nothing changed and firewal continue restarting by himself.
Last logs I received before crash were:
%ASA-4-711004: Task ran for 35 msec, Process = Dispatch Unit, PC = 84a619e, Call stack =
%ASA-4-711004: Task ran for 35 msec, Process = Dispatch Unit, PC = 84a619e, Call stack = 0x084A619E 0x084A6512 0x084A70E1 0x084A7987 0x084A7AAA 0x08558B9B 0x08558E8A 0x083D3518 0x083CA145 0x080659D1 0x089196D9 0x08919790 0x089FF711 0x08A27468
