For the archives (and because I was asked to do so): here are the
exact commands I used to fix the problem.

Because I had already updated the BDB package whe I noticed the problem
with Cyrus I unpacked the old one to /tmp/db4.old and did

$ PATH=/tmp/db4.old/bin:$PATH
$ LD_LIBRARY_PATH=/tmp/db4.old/lib
$ export LD_LIBRARY_PATH

to use the old db_* tools by default.

After stopping Cyrus I checkpointed the db log and perfomed recovery:

# db4_checkpoint -v -1 -h /var/test/db
db_checkpoint: checkpoint: Thu Jan 27 21:59:13 2005

# db4_recover -v -h /var/test/db
db_recover: Finding last valid log LSN: file: 8 offset 4562006
db_recover: Recovery starting from [8][4561817]
db_recover: Recovery complete at Thu Jan 27 21:59:28 2005
db_recover: Maximum transaction ID 80006892 Recovery checkpoint [8][4562103]

I removed the log file

$ rm /var/imap/db/log.0000000008

reset my environment (PATH, LD_LIBRARY_PATH) and started Cyrus.


HTH, Jukka
