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...
