I have PIX 520 with "PIX Version 4.2(4)". Some inside workstations are permitted to go to Internet through the PIX using NAT and Global commands.
Suddenly some of the workstations can't reach the Internet, and I must do "clear xlate" to enable them to reach the internet again
Are threr any fix?

Please execute a show version on see if your PIX has a limited session license. It sounds to me that you´re having a limited session license, while having more internal users then your license. This would give this kind of behaviour.

The "show version" results stated that:
PIX version is 4.2(4) with 8 MB flash
and 128 MB RAM, and it's unlimited license.
On the other hand, this PIX with the same configuration was working properly for 2 years before I get the current problem

Hi -
Can you post any syslog messages when your inetrnal users get dropped.
Thanks -

Hi,
I have had a similar problem (interface stops forwarding for all stations on one interface).
After several months of problems we made a TAC case of it, and after several things trying (TAC could not determine the problem) we did one thing that gave the solution. What we did?
We disabled all logging!
After talking to TAC again we believe that the PIX 520 does not handle logging buffers to well, and that at some point CPU or memory loads peaks when it is logging, causing to stop an interrupt (sometimes it where two interfaces stopping and even sometimes the whole PIX booted spontaniously)
Don't know if this can be the cause of your problems to, but it is worth a shot, don't you think? So, I would disable all logging for a while, and see if problems are over.
Kind Regards,
Leo
