FC4 and Zimbra 3.14 on Dell 1.2Ghz with 2.5Gb memory.

Seems that zmlogprocess uses 4 minutes@100CPU to process and does this every 10 minutes via crontab so, not needing graphs THAT bad, can I run this process once a day, say at at 00:15, to just get the daily mail report instead?

Doesn't seem like I had this issue before, though looking through the "stats" posts here, see alot of posts RE: this issue.
Anyway to clear out all of the old stats?
