dovecot-uidlist invalid data

[Király Balázs]

Hi!

 

I'm struggling with the following error: 

 

Aug  4 21:32:00 mx02 dovecot: imap(xxx at xxx.tld)<17693><w14vpU+PCCSwPxpo>:
Error: Mailbox INBOX: Broken file /home/vmail/xxx.tld/xxx/dovecot-uidlist
line 6246: Invalid data:

Aug  4 21:49:22 mx02 dovecot: imap(xxx at xxx.tld)<21879><YNhW40+PLoBOGLlU>:
Error: Mailbox INBOX: Broken file /home/vmail/xxx.tld/xxx/dovecot-uidlist
line 6249: Invalid data:

 

It seems the first part is not incremented properly and sometimes it has a
jump in it, like the line 6246:

 

18810 :1564935891.M816284P8904.mx01.m.ininet.hu,S=12145,W=12409

18812 :1564947092.M542714P2651.mx01.m.ininet.hu,S=12275,W=12517

 

Even though I deleted all the dovecot* files the error comes back. I have
the maildirs through NFS, but I set to store the INDEX files locally. 

 

I have failover configuration, that means when one of my servers die another
one takes the active IP and start to serve dovecot users, so its always one
server that serves all the users, no load balacing.

 

Any idea what am I missing or how could I fixed this problem?
