Hi, I have a linux dedicated server running Debian Etch, kernel: 2.6.18-6-686-bigmem, I have 4g of ram, without -bigmem it only sees 2g of ram.
A few days ago I noticed that my ram was at 100% usage and I cant figure out what is using it and if its normal. The only services I have are: 2 CoD4 servers, Asterisk, and DirectAdmin. After a reboot the server consumes ~800mb of ram and about 24 hours later it will use all 4g of ram.
Can anyone provide any insight as to what's going on? I have read some articles that say large ram consumption is normal on linux but others are telling me it's not normal to use all 100% of the RAM.
Here are my free -m output and top output sorted by %MEM
Its been 24 hours after last reboot and I had a friend make some configuration changes it seems to be handling ram slightly better as its only using 3g right now.
