Hardware: 4xP3-550 16Gig of Ram 1x18Gig internal disk 4x54Gig RAID Disk 512Meg swap partition on sda2 1Gig swap file in /usr/local/swapfile on /dev/sda3 The 4 54Gig disks are in a Raid5 with software raid. I'm on a vanila 2.4.18 kernel configured for Huge Memory. This is supposed to be a new corporate mail server but we're having some issues. What we have been see'ing the 3-4 times we tried is the Load jumps to 9+ and the box drops to a crawl when we rsync the imap folders from the old host to the new host. Last night I readded the 1Gig file (it was at 512Meg only) and we started again. It ran great for about 2hrs then the box locked up. I got to the console this morning and it was scrolling so fast I couldn't even read it. It looked like it was reporting ACIC errors on a CPU but couldn't quite be sure. It required a hard reset as it was unresponsive to c-a-d and sysreq commands. There is nothing in the messages file and there was nothing useful on the console. "free" shows the rsync eats up alot of memory but never starts to swap or if it does only swaps less than 30k. Thoughts? :wq! --------------------------------------------------------------------------- Robert L. Harris DISCLAIMER: These are MY OPINIONS ALONE. I speak for no-one else.
