    After the fresh installation of both FC4_64 with plesk8, I don't know why the memory is keep increasing (1GB RAM) after reboot it uses 40% and it will keep rising up till 90% and up, I don't know this is normal after plesk installation or not, anyone experience this? and by the way, should I run change the run level in inittab from 5 -> 3 to free up the memory from x11?

    I have seen the same thing. Memory slowly creaping up to near 100% on my box. So far no problems but I have not identify yet what is leaking. If I get some more info will post it here. Has anyone else seen this yet?

    What processes are running? Keep in mind that Apache does tend to prefork a lot of child processes.

    I have look at the all process in the system monitor and they are as shown, I wonder that if I sum all the memory used in the column, I will exceed the number of RAM I have. So how do I get the exact processes that currently used the memory.

    (if the picture is not attached in this post,,,,I have to say sorry, but I got it from the system monitor tools)

    Spamassassin is killing my server.... so it might be a place for you to check.
    When spamassassin is running, the server load cranks up to 12 or 13... the server *used* to average 0.4 at a high end with it's 1536mb RAM... but now it's sitting at 5.1 on a low end. The only thing that has changed is Plesk 7.5.4 to Plesk 8.0.0. And it's spamassassin that's always sitting at the top of the process list on a "top" query.

    This is all of course only when spamassassin hasn't died on it's own, and stopped filtering mail (it still runs, but doesn't catch anything, and the headers show a ? for the score).

    My spamassassin simply stops itself randomly. Nice to be paying for something that doesn't even work... when it runs, I might get 2 or 3 spam a day slipping through. Since the upgrade to 8.0.0, I'm lucky if all I have are 300 spam messages 'slipping through' due to a failed spamassassin.
    So essentially, I get to pay for something that doesn't even work, or pay for something that doesn't even work, but also kills the server.
    Choices, choices...

    what version of spamassassin did you use before v8? if it was 2.6x you better check the spamassassin website to read the upgrade docs. Their is a new way of bayes checking in spamassassin 3.x that needs some manual conversion. We had also a high load when we upgraded spamassassin even on out Plesk 7.5.x box.

    I have also used the 2.6x and the 3.1.x builds, and have had the same results each time. I've gone far enough to completely remove all traces of spamassassin and start fresh as well.
    This is leading me to believe that it's not spamassassin, so much as how the qmail bild that sw-soft is distributing is communicating with spamassassin.
    I noticed the load drop minorly when I set a 3 hour cron to restart spamassassin, and remove psa-spamassassin. But I don't see why I should be having to do this, as it's something that I am paying for... so it should work.
    Something that sw-soft changed for 8.0 is seriously screwing up people's servers, and I would honestly like to believe that they are working to fix the problem. But my hope is fading fast... as is my willingness to continue using their control panel.

    if you run spamassassin -D --lint does it give errors or timeouts?

    I removed it from mine, and the load dropped instantly. And not a minor drop, either. Like, from the 8+ that it's been running at since the install of 8.0.0, to the 0.4 that it was running at with Plesk 7.5.4.
    This of course makes sense, since spamd is monopolizing the top spot in a 'top' query through SSH...

    What do you get when you run top?

    when in top press O (capital O) and then q (small q) and then hit enter. This will sort processes by resident memory usage

    Other than removing spamassassin? None yet... sw-soft does not seem to acknowledge that there is a problem. There have been several patches released for Plesk 8 so far, and not one has even come close to fixing this problem.
    I've tried removing spamassassin, removing psa-spamassassin, and tried various versions of spamassassin (2.x and 3.x), and the load remains astronomical as long as spamassassin is running.
    This is telling me that the problem is not spamassassin, but infact the qmail. Why would it be spamassassin anyway? I've tried several sources now, and everything was working happily with 7.5.4, and it was qmail that I updated... not spamassassin.
    They really screwed up this qmail build... from this, to mapping users to UID incorrectly and screwing up root deliveries. I'd like to think a fix is being worked on, but as I've mentioned before, I'm not holding my breath and waiting. Why fix a bug when you can add a new useless feature instead?
    CPanel is claiming to have support for Apache 2.x in the next month or two. It's looking better and better all the time, since I would get bundled from them what we are paying massive ammounts for now. Spam support, application installer, gameserver module, OFFSITE FTP BACKUP (!!!), global clamav support for scanning both mail and directories...
    I really don't want to leave Plesk, but if it's developers are not going to offer stable software and are not going to support their customers, I can't see myself continuing to pay these prices to be a beta tester.
    Having an average server load for the past 2 weeks of 10.7 is just a bit much for what is being paid for this software...

    well, a little bit of progress .. has to me plesk internal problem.

    When i leave the spamd running, but turn off the filter in plesk interface (Mail --> remove the checks in front of global und user settings) the memory gets flushed immediately.

    Something about the internal handling between plesk and SA is not right, causing it to spike.

    SWSoft please do something. SA is (nearly) the only half-decent means to stop spam ..
