Memory Usage on PUIX 525 With Multiple Contexts

Unanswered Question
Mar 2nd, 2007

Hi,

We have a customer with a PIX525 configured with two contexts. When displaying memory usage in one of the contexts it reads memory usage of 453%(approx. 1.2Gb) & the PIX only has 256Mb installed.

The PIX is operating fine but I'm concerned with memory usage & how it has arrived at these figures.

Comments appreciated.

Thanks,

Pete

I have this problem too.

Many enhancements have been made to provide improved monitoring of the system operation and to help isolate potential network and security appliance issues. To monitor and to troubleshoot memory usage levels or potential leaks the show memory command was enhanced together with the addition of a show process memory EXEC command.

The show resource and show counters commands provide detailed information about resource utilization for the appliance and security contexts as well as detailed statistics. To monitor the CPU utilization you may use the new show cpu EXEC command as well as the enhanced show process cpu-hog EXEC commands. To isolate potential software flaws the software introduces the checkheaps command and related show EXEC command. Finally, to get a better understanding of the block (packet) utilization, the show blocks EXEC command has been enhanced to provide extensive analytical tools on block queuing and utilization in the system.
