Pix 515-E running V7.1.2 had stopped forwarding trafic 3 times over a 4 weeks period since first installed. When problem happened, it can not be ping or ssh to, it stopped traffic going across it. Console still works. Restarting the box would fix the problem tempoparily. I managed to get a show blocks while there was problem as shown below. The line 1550 block does not look right. Can anyone confirm if problem is related to V7.1.2?
