Everything seems to have been working fine for a few days (with the
problem account switched off), so I thought I'd re-enable it and see
what happened.

First I switched it back on the server. No problems. CPU remains normal.

Then I switched it on on the client. Again, no problems. Connections are
being made and data is being backed up, but load on both client and
server seems to be fine.

I made some changes to the backup configuration so that most of the mail
spool is started from scratch. CPU and load averages increase on both
boxes, but never hits 100% for more than a few seconds. Backup continues
over a period of 7 hours with CPU usage generally staying below 50% and
load averages below 1, and then the levels go back to idle. Store has
increased by around 11Gb.


I guess I'll have to try backing up from scratch again to see if I can
recreate the problem.
