Server load goes from 0.03 to 6.13 during the day. Usually, server load is higher during the morning (PST).
One thing I don't understand, they say on their pages backups are done during the night but this is the second time backup is being processed during the day. I won't bother support again but it really puzzles me.
I know that loads between 6's and 9's aren't so high but I can't feel safe when services like Eximstats starts to fail.
Thank you for for your comment on the issue, ThinkSupport.
