[Dovecot] Couldn't init INBOX: BUG: Unknown internal error

[Philipp Schmid]

hi,

I'm getting quite a few of these in the logs of our new dovecot mail  
server:

Aug 20 09:50:03 mail2 dovecot: POP3(vwc406): Couldn't init INBOX: BUG:  
Unknown internal error
Aug 20 09:50:03 mail2 dovecot: POP3(vwc406): Mailbox init failed  
top=0/0, retr=0/0, del=0/0, size=0

we migrated from courier and other mailboxes work.

any idea what the cause might be or how I can fix it?


greets philipp
