db4 Permission denied

[Ing. Andrea Vettori]

Hi,

today I had a problem with a Cyrus server that was ok since a long time.
The server has less than 200 users but a lot of emails (about 40 GB in
620.000 messages).

Relevant log files are below. From that point after, lmtpunix died every
time it was called until I deleted the content of the db directory and
deliver.db and restarted master.

The content of the db directory was the following :

total 11460
drwxr-xr-x    2 root     root         4096 Oct 11 12:54 .
drwxr-x---   13 cyrus    mail         4096 Oct 11 15:25 ..

-rw-------    1 cyrus    mail            4 Sep 22 19:36 skipstamp

I have no idea why log.0000000018 has permission root:root.

Any ideas ?

I also noticed that tnx number are very high and the last one was
2147552789 that is near the max value of a four bytes signed integer.
Is normal to see such high numbers ?

Thank you
