I had a hunch Oracle was involved in this problem. Oracle allocates plenty of RAM but does not actively touch all the pages. This causes the kernel to mark the pages as inactive and candidates for swapping to disk. Oracle has plenty of knobs, both within Oracle as well as the OS, that you can tweak. Consult the docs. On systems with huge RAM (> 16GB), kscand/kswapd can hog CPU. There are work arounds/patches for this problem. Check if your server is having this problem and needs fixing. - Raja _______________________________________________ To unsubscribe, email [EMAIL PROTECTED] with "unsubscribe <password> <address>" in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
