Bellow you will find the description my colleagues sent. A memory increasing problem risk to provoke a general outage at the plenary (Client coference we run) that is running in Japan today.
- SEVERITY HIGH : PIX FW version 8.0.4 memory increasing problem
The upgrade of the IOS on the PIX from 6.3 to 8.0.4 has fixed the problem on the VPN Client which used IPSEC. However, this has introduced a new problem. The memory usage on the PIX is continuously increasing until the max. When it reaches the limit of the capacity, there are no Internet Access here.
It has happened around 10:00 this morning. We have decided to failover the Standby unit.
But, The standby unit has a copy of the memory content thus we were in the same situation.
Finally, We have shut down the Standby unit and start the Primary one.
After the start-up we had only 84MB used now it is increasing by 25MB every hours.
We suspect 2 processes on the PIX:
Dispatch Unit and Unicorn Admin Handler are 2 processes that used the biggest amount of memory and they are increasing.
Thanks in advance for anything you can do to help us to resolve this critical issue.
