 Posted: Wed Apr 26, 2006 10:50 pm Post subject: Pix 525 running 7.1(1) dropping packets |
 |
|
I recently upgraded to 7.1(1) on the pix 525 and have this problem that
every 4-5 days or so the firewall starts dropping packets, internet
access is slow or non-existant. I use the blue cisco cable to
establish a serial connection to the firewall, and am either not able
to ping hosts at all, or I get a 20%-40% success rate when trying to
ping. Whether I ping the outside router, inside hosts, or dmz hosts,
its the same result. If I reboot the system, then seems to fix the
problem completely (until the next time, when it starts all over
again). I am not running any logging on the server, so its not a
question of the flash filling up.
Has anyone else had this problem ? |

I would be interested to know whether "clear xlate" or "clear local" affected
the situation?

But RAM might get fragmented. Try "show mem" -- in 6.x anyhow, that
shows the number of entries in each of the size pools. Normally the
values are nice an pyramidal, but when things go worng [at least in 6.x]
the numbers invert. I don't have a sample to show you, but when you've
seen it once you'd recognize it again. |

Actually I think this is the problem, show mem, shows the used memory
steadily increasing. At the rate its going, it seems like it will
overflow in about 4-5 days. This seems to be a memory leak -
Do you know if upgrading to 7.1(2) is supposed to resolve this. I
didnt upgrade to 7.1(2) because of reported problems of the inside
interface dropping packets actually. |

Sorry, I don't know that. You could try looking through the bug lists
in the 7.1(2) release notes. |
