    Default Zimbra Memory Utilization

    Hi,

    Can someone tell me if this is normal. Running Zimbra NE 6.0.10 on Centos with 32Gigs of Memory. Over time, my memory drops to 200Mb free. Is Zimbra that memory hungry?

    log in as root..run free. what is in there? if you aren't swapping yes this is normal...anything not used by zimbra will be used by Linux for caching..

    I'm not swapping. So Zimbra takes all the memory it can get?

    free -m
    total used free shared buffers cached
    Mem: 32183 14874 17309 0 2552 6031
    -/+ buffers/cache: 6290 25893
    Swap: 34812 0 34812

    That is normal Linux behavior.

    Run htop instead of top and you should see the actual memory usage. the rest is cache/buffers.

    Linux tends to cache a lot of stuff and when an application requires the memory it will just drop some of the stuff in the cache and use that for the app.
