Yes, I know it's old, but it's been rock-solid, and migration to a new server would take days to accomplish, but I fear that's what I'm faced with.. Specs on the server: Dual Xeon 2.8Ghz / 4GB / ~35GB RAID-1 (system) / ~105GB RAID-5 (mail storage) For the last week or so, I've been getting spurts of MySQL connection failures in my mail logs, but the total number of connections never even comes close the max connections allowed for the server. Occasionally, our website will appear to completely stall for a few seconds, and most frustrating of all, when I'm poking around in a shell, things will sometimes hang for several seconds while performing certain tasks (like cd, ls, tail, etc...). Even top took like 8 seconds to start displaying a process list. According to raidutil, both raid volumes are optimal. Nothing shows up in syslog. Here's some info from top(1): last pid: 8799; load averages: 0.20, 0.43, 0.38 up 35+23:48:22 14:11:46 263 processes: 2 running, 261 sleeping Mem: 1027M Active, 2100M Inact, 393M Wired, 178M Cache, 199M Buf, 75M Free Swap: 4096M Total, 72K Used, 4096M Free I'm at a loss as to what I should look at next... anyone have any suggestions before I commit myself to a VERY long weekend moving everything to a new box?
