Problems on RaQ3 and 4

Every day at exactly 1:15 i receive this message by email from my cron deamon:

NOTICE: Index pg_attribute_attrelid_index: NUMBER OF INDEX' TUPLES (574) IS NOT THE SAME AS HEAP' (561)
NOTICE: Index pg_attribute_relid_attnum_index: NUMBER OF INDEX' TUPLES (574) IS NOT THE SAME AS HEAP' (561)
NOTICE: Index pg_attribute_relid_attnam_index: NUMBER OF INDEX' TUPLES (574) IS NOT THE SAME AS HEAP' (561) META vacuum - FAIL: ERROR: cannot find attribute 1 of relation quota
About 45 minutes before that, i get this email:

Memory on the Sun Cobalt server is heavily used.
The Sun Cobalt server needs more memory than it currently has. Consider adding more DRAM to the server.

Total memory is: 651640 KB
Used memory is: 633272 KB
Free memory is: 18368 KB
Percent used is: 97
Only during that time the server is heavily loaded, while normally its quite idle. I logged in through ssh at the time the server was heavily loaded (ssh and the admin nearly worked) and saw there was a progress gzip which was taking extremely much cpu usage.


Also i receive these emails lately from 2 of my servers (raq3 and 4):

The original message was received at Mon, 19 May 2003 06:42:16 -0600 from [218.70.117.225]

----- Transcript of session follows -----

Im only hosting kalvaz.com and have never heard about doreen.. the email itself is very odd too:
