I may have done something dumb with Suexec

[unsichtbare]

I was fighting a high server load and installed php5-xcache but still had high load. 95%+ all the time. In top, there were many processes assigned to the user www-data, so I unchecked the Suexec box in Management > Server >Settings and restarted the system (init 6)

On restart, things weren't much better AND I couldn't access my mail accounts, so I re-enabled Suexec and restarted again. Now I can get mail in all but one of my accounts. I could delete the account and set that up again, but I would like to know what happened? Also in top I see only processes owned by root and occationally www-data for apache2.

Oddly enough, none of these settings had significant impact on the load, but when I re-configured my Ubuntu virtual machine (VMWare ESX) for dual proc instead of single the load dropped from 95+% to <5%.

Am I in trouble with my mail accounts?

Any errors in your mail log?

[unsichtbare]

These errors were in mail.warn at the time Suexec was unchecked:

And this is what is in mail.log when I try to log in with an account that was working:

Jan 1 08:26:43 clients1 courierpop3login: Connection, ip=[::ffff:24.121.xx.xx]
Jan 1 08:26:45 clients1 courierpop3login: LOGIN FAILED, user=web4_john, ip=[::ffff:24.121.xx.xx]
Jan 1 08:26:50 clients1 courierpop3login: Disconnected, ip=[::ffff:24.121.xx.xx]

It seems to be only the one mail account!

This is the output from top, does it seem normal?
