    Default Extremely High Memory Usage for Amavisd

    Greetings. We are a network edition customer, building a new Zimbra v4 server within VMWare Server v1. The guest O/S is Fedora FC5.

    Installation went well, and the server appears to be up and running with just one mailbox at this point. However, we're hitting a major snag with respect to performance. Amavisd appears to be using close to 90% of available memory. Please see below:

    Mem: 1035428k total, 1023428k used, 12000k free, 924k buffers
    Swap: 3068336k total, 946532k used, 2121804k free, 11948k cached

    PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
    700 zimbra 18 0 1685m 881m 592 D 13.3 87.2 0:26.70 amavisd
    In the Admin UI, if I go to servers > my_server and turn off the 'antispam' and 'antivirus' services (then restart zimbra from command line) the system works well, and is quite responsive. Re-enabling these services will bring the machine to a crawl. (I'm seeing 1/5/15 min system uptime values in the 15.0 range.)

    I thought there should be $max_servers (per amavisd.conf) pre-forked amavisd children, each using 40MB-ish of RAM each, rather than one monster process using close to a Gig??

    Any suggestions would be highly appreciated...

    Thanks,
    -Dave

    Default Compatibility

    The Open Source edition built specifically for FC5 works fine...

    Going to scrap FC5 and try Network Edition on CentOS 4.4.

    holy cr$p, that can't be right. iirc amavis master spawns the children which share memory, but a res size of nearly 900mb gotta mean somethings gone horribly wrong...

    i wasn't aware fc5 was supported for the network edition, if you're trying to run a different version, say rhel4 version, on fc5, this may have arisen due to some issue with perl libs - amavis does preload a huge amount of perl.

    It isn't, a supported operating system is needed and a well specified virtual machine (I would suggest) is also needed.

    I belive the problem resides in the DB_File version used by Zimbra:

    Manually running amavisd as the zimbra user results in the following:

    ./amavisd[16084]: SpamControl: initializing Mail::SpamAssassin
    Use of uninitialized value in numeric ge (>=) at /opt/zimbra/zimbramon/lib/i386-linux-thread-multi/DB_File.pm line 271.
    Use of uninitialized value in numeric gt (>) at /opt/zimbra/zimbramon/lib/i386-linux-thread-multi/DB_File.pm line 275.
    Deep recursion on subroutine "DB_File::AUTOLOAD" at /opt/zimbra/zimbramon/lib/i386-linux-thread-multi/DB_File.pm line 234.

    I solved it by prepending the path to my own DB_File in .bashrc in /opt/zimbra:

    PERLLIB=/usr/lib/perl5/5.8.8/i386-linux-thread-multi:/opt/zi...

    Apart from this the only fixes I did was the normal libssl linking fix for fc5 (but linking to libssl.so.4) to get LDAP to play ball.
