    RAM hogging and Plesk. I'm new, be kind =D


    Recently I rented a CentOS-based VDS from GoDaddy. The first two months everything was fine, then I noticed a serious peak in my RAM usage as reported in Plesk (9.5.2), running steady at 650+MB and peaking at 800+. This was causing services to stop, as the VDS only had 256MB guaranteed with 1GB burst.

    Thing is, I can't figure out what in the hell is eating so much, and why the top command is reporting a lower figure than Plesk is reporting. See the screenshot for more details there.

    I'm 100% new to Linux servers. I've been in web marketing and worked with some minor development stuff, so I'm not stupid, just new.

    use free -m command to see actual free memory

    Code:
                 total       used       free     shared    buffers     cached
    Mem:          3267       3173         93          0        143       1366
    -/+ buffers/cache:       1663       1603
    Swap:          298          2        295
    2nd line is most important, this shows how much is actually used/free and not taken up by buffers and cache
