4G of ECC with no log of error, I dont think that in this case the
RAM is the guilty.

Other factor: this corruptions appeared with the volume of use,
this smells 'race' badly.

Example of the simptom:
Sep 15 21:17:14 mupdate mupdate[1608]: DBERROR: skiplist recovery /var/lib/imap/mailboxes.db: 14D67FD8 should be ADD or DELETE

When this happens mupdate get tired of create threads to the
point of 'cant create another thread'.

Whe are using CentOS 3.0 (if kernel/glibc/library versions
can mean something).

(Our backends are CentOS 4.1 64 bits, our mupdate is
CentOS 3.0 32 bits).

Any more relevant infos?
