But I am by *no* means an expert or even an amateur. I do suspect that the problem wouldn't be easy to isolate since it's not a bug per se. Not sure what kind of metrics you'd even employ to figure out if something like that was happening.

All we know is that hard drive failures are pretty common for haven.



Someone call hetzer and tell them to switch to Seagate or Western Digital HD's. whatever they are using are shite obviously.

Hey, that's an idea to help absorb some of the costs, offer "Stress testing" services to hard drive manufacturers, how many HD's can Haven kill? Can they build an Haven-Proof drive? These and many other questions may one day be answered.

The problem is that he's hosting the server on HDDs. He should be using SSDs, minimum. A game like this causes a LOT of strain on the hard drive because of all the read/write data it requires to update tiles. I used to run one of the largest Minecraft servers in the world and we had the same issue until switching to SSDs/RAMdisk.

Now, I don't know which specific hosting package is being used... but the lowest one comes with 16GB of RAM which should be adequate to run this server (although 32GB would be better) and an i7. Personally I would go with a Xeon minimum (and if they're using an i7 that would be one of the causes of random lag spikes) but overall the I/O is the bottleneck for a server like this and a 7200RPM HDD just doesn't cut it.

Not only would a 7200RPM HDD (or even a 15k SAS) be bottlenecking the server performance, it would also be taking a lot of stress from doing such and thus failing more often.

Can we make it a rule to back up your claims?

Sure thing. http://www.teamliquid.net/forum/viewmes ... _id=157898

Was bigger than Reddit, Curse, and every other major server except for Massivecraft.

Feel like a retard now? You probably should. If you were at all involved in the Minecraft community you'd know my name, anyway. I've been a major part of it since alpha and all through hMod, Bukkit, and Spout. But you don't, because you're a nobody. Get on my level :)
