5.3.2 Host Server Page Faults on AIX 5.1

Since we upgraded to 5.3.2, page faults have increased dramatically from an average of about 500/day (peaks of 1000) to an average of about 2200/day and peaks around 4000.  We noticed in the monitor utility that the PID representing the host server had a lot of page faults and may be the culprit — com.hie.cloverleaf.remoteserver.CloverleafHostServer

Has anyone else see a rise in page faults after upgrading to 5.3.2?  Is this version of host server prone to page faults?
