Default Memory Leak

Hi, I am trying to track down a supposed memory leak. All I know
about the problem is that the memory gets up to 90%, and then we have
to restart the application and database.

In glance, I view the processes, but it doesn't seem to be all of the
processes. ps -ef | wc -l shows 534 processes. When I check glance,
it only shows about 20.

Also, if I look in top, it shows the RSS size of all the processes,
but I don't know if I can list the processes by RSS size. I don't
think that top is as accurate as it could be. Also, if you have any
other tools to find which process is causing the memory leak, please
let me know.

Thanks, Margie

If you have access to HP's ITRC Knowledge Base, take a look at a document
titled something close to "How to account for memory usage in HP-UX".

It will provide info on the tools and procedures you're looking for.

If you want to see all processes, you must turn off filtering in glance
menu.
