We also had a load increase (about 10x) when going from 1.1.10 to 2.0.7 a couple of weeks ago. It ended up being due to a slight increase in memory usage by the imap processes that made the servers start using swap and the load to spike. A memory upgrade brought it all to normal loads. Wonder if this is your case (vmstat, check for si and so). -- Jose Celestino | http://japc.uncovering.org/files/japc-pgpkey.asc ---------------------------------------------------------------- "Assumption is the Mother of Screw-Up" -- Mr. John Elwood Hale
