High memory usage

Your server was restarted at this time because it was using more than 1000 MB of RAM. If this happens repeatedly, please investigate any plugins as possible causes and consider contacting us for further assistance.

Is it something i have to be concerned about.I have a 4 core VDS managed (DALLAS).
I know my red orcestra 2 server was DDos Attacked on the 30th august.

cheers.

If you are running mutators or custom maps, I recommend looking at them to see see if one might be causing this. If not, the game itself may have a memory leak. If you aren't restarting your server daily, I recommend re-enabling that option; if you are already restarting your server daily, you could consider turning off the memory check and monitoring your memory usage manually.

custom maps have been disabled a couple of weeks ago,Im not running any mutators.
Ive disabled the server for auto restarts because i have to manually add the bots,they dont stay for some reason.Thats some issue with RS itself im guessing anyway.

I will do manual restart when the server is empty instead i guess.Server is mostly full of 64 players everyday at certain times in the evening.
