Anyone who uses my mail server will know this has been a bad week. Monday the ISP had a bad day - which meant I did too. Anyone who visited my site on Wednesday ( today ) before about 3pm (Aust EST) probably saw the message saying the database server went bang. Everything is back to normal now...but it's been a busy week. Earlier this week our ISP had a denial of service (DoS) attack launched against them which knocked out my connection for the better part of Monday. The equipment was fine, but no-one could reach it.
Then this morning I came into my study (where the servers live) and noticed it was a little warmer than normal. Then I noticed the database+mail server was hot - as in too hot to touch. Hmmm. That's not good sez I. It was running a Distributed.net client which uses any spare CPU cycles and can cause a bit more heat build up than normal....but nothing like this morning. Anyway, while I was trying to figure it out (all of about 2 minutes) the server did a thermal shutdown, meaning the CPU hit 75C!! Not good :(
When I looked into it further I found the cooling fan in the power supply had seized. As in locked up tight. Grrrr!! So off I went to the local electronics supplier, got me a new 8cm 12V ball bearing fan and fitted it to the power supply. The powered it back up whilst holding my breath and crossing fingers, toes, arms...everything. To cut a long story short, I'd fried one of the 64MB memory modules which has taken the useable RAM down to 448MB. Bummer. RAM is cheap, so I'll probably lash out an buy some nice new stuff and go all the way to 1GB or something stupid :)
Well that's the story of my week with these systems. Hopefully things will return to their normal, stable, routine and I wont have to do anything except watch the lights blink occassionally :)
