I've been trying to identify a problem that I am experiencing on one of our Centos servers. The kswapd0 process runs close to 100% most of the time causing consistently high %IOWAIT times. The servers is running 11.5.1 with appserver connections to the DB. If I run a free -m this is the result, indicating i have plenty of memory available. total used free shared buffers cached Mem: 9888 9779 108 6509 0 6538 -/+ buffers/cache: 3240 6648 Swap: 9997 3348 6649 What I have identified is if I run the proadsv -keepservers -stop command the kswapd0 process goes away and %IOWAIT time drops to acceptable levels (under %5 as apposed to 10 - 20). The second I bring up the proadsv process performance drops. Any ideas how I can tweak the OS or the AdminServerPlugins.properties file to reduce swapping to disk.
