dovecot-uidlist invalid data

4 Aug 2019


      Hi!
I'm struggling with the following error:
Aug  4 21:32:00 mx02 dovecot: imap(xxx@xxx.tld)<17693>:
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@xxx.tld)<21879>:
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?
