Hello List! I'm trying to discover what might possibly be running at 4:00 AM on all my penguins that might cause excessive cumulative VM paging (we're over committed real by 12-18%) at one time.
Obviously something appears to be configured on all systems to do the same thing at the same time. That said here's /var/log/messages from that time period.

I would expect to have seen massive swapping internally to Linux before a VM paging event that would come close to exhausting the page pool because of excessive real and xstor usage. We're looking to set up some cron fired snapshot scripts to give us some data on the time frame in question. Can anyone tell me (Yes, I know we need a Linux monitor package. I also know we're never gonna get one) if there are any stock items like top that can give me a list-of-the-moment of what process is using memory, or a method to make top display max storage rather than max CPU? Also rcd/rug seems to have gotten installed on the last round of maintenance as I don't see the 'unable to downloaded channel list:' messages prior to that date. Since it appears to be broken, do I need it? Can I remove it? Thanks. -J ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
