NetBackup master host is swapping like crazy even though memory usage is only at 40%
just wondering if anybody came across this and if it might be related to NetBackup. We have a Solaris 10 Server with only a NetBackup 220.127.116.11 Master installation running. I was now contacted by our operations that they keep receiving error messages from their monitoring that there is a high amount of page swaps going on. Yet when they check the memory usage it's usually at around 30% never above 50%. We have a total of 32GB RAM installed which should be plenty. When looking at the running backups I also don't really see a performance degradation, though it's hard to really tell if there is no impact. Apparently the 'issue' has been going on for a long time so it does not seem to be a new behaviour.
Could this be some function/feature from NetBackup, anybody has any smart ideas on how to further investigate this? (My Solaris know-how is rather limited I am afraid)
As always any help would be greatly appreciated!
