(our server today, the brick symbolizes the users)
As you all noticed, today the server kept crashing like mad. It wasn't any particular error - I checked the logs and the Windows Error Reports - it was just that we were running out of RAM. :-(
The virtual machine we are running the MineCraft servers on has 7 GB assigned (now 9 GB due to SaintK's emergency intervention) - it might seem a lot BUT we're running SMP on it now (2 GB), there was a Natural Selection 2 Server (1 GB), fCraft - usually low on memory usage BUT we had 40 players today - when they start joining multiple maps (which are all huge), the server can easily go to ~1.7 GB or so - not counting the two other MineCraft servers. In the end there's also MS Exchange Server, which is what this machine used to be mainly configured for, that likes to have RAM spikes, especially when running some indexers or whatever kind of crap it's doing - apart from normal functionality.
Now - long story short: WE NEED RAM; another 4 GB die to be precise.
SaintK looked it up and the RAM we need would cost around 111 Euros. We're not demanding donations and not saying that the servers will go down without them - SpA always finds a way, but we ask you politely, if you have some spare change, please consider donating. Every bit helps, since we have the monthly server operating costs to cope with already.
