    After the upgrade from 7.5.3 to 7.5.4, i have extremely high CPU usage.

    Currently is arround 24.34, but i saw numbers like 30 and even higher.

    Server is extremely slow, and services keep shuting down every few hours, the server is completely unstable.

    I can't figure out what's going on.

    First make sure you either disable or uninstall the Plesk Watchdog software...

    Edit: My bad, I could swear I saw watchdog in his list.... disregard my post.

    Is that a module?

    I don't see it. I probably don't have it installed

    You don't have it installed, it's not in the list you posted.

    If you watch 'top' for a while do you see any odd processes eating away at your resources? This could really be anything - hardware failure, hacked box, rogue script, misconfiguration, anything.

    In addition to Cranky's suggestion, this happened when I updated Spamassassin to version 3 via ART's qmail-scanner. Both spamassassin and psa-spamassassin were running at the same time and chewing up resources.

    We are having the same trouble on one of our RHEL3 ES box PLESK 7.5.4.

    So far it looks like MySQL is dumping constantly:

    84.5% CPU /usr/libexec/mysqld --defaults-file=/etc/my.cnf --basedir=/

    It appears to be occurrring from the cronjob:

    */15 * * * * /usr/local/psa/admin/sbin/backupmng >/dev/null 2>&1

    But I am not possitive of this yet. Any one else see this happening?
