URGENT: j2pg process eating lots of CPU

[Johuak]

I am running with AIX 5.3 TL06. System's CPU usage was very high so i checked topas and i found that there is one process running by root which is j2pg and that is eating most of CPU. I googled on j2pg and found that it start becasue of lots of I/O on system.

That is true before because couple days DBAs are doing extreme work on system and that might caused I/O problem and that may have triggered j2pg process.

But my question is now no one is doing extreme work on system still j2pg process is using same amount of CPU. Does anyone have any idea about how to stop this j2pg process? This process doesn't show in ps output may be because it is kernel process?

Name PID CPU% PgSp Owner
j2pg 139356 29.0 1.0 root

To tune this out you'll need to increase the JFS2 fsbufs, lower the JFS2
read-ahead, and turn on the release-behind on the jfs2 filesystems.
