Hi,
We have an issue on our lpar where the pin memory usage slowly and regularly increases approx 1.5% a day until it reaches its 80% threshold
We have to regularly reboot the lpars to release the pin memory as we have found that killing all processes does not release it.
However, obviously this is not a real solution.
I have monitored any constantly running processes that increase in memory usage with time by monitoring the output of ps vg. The only one I found of any significance was xmwlm stats recording service which I stopped, but pin memory usage still increased at the same pace.
Is monitoring svmon -P going to help me find the cause of this issue and if so, monitoring which figure in following example of a process when running svmon -P, will show me the process is increasing in pinned memory usage to cause the increase we are seeing. I know the obvious answer would be 'the one that says pin above it' but there are three of them in the example.
