[BUG] client state / Message count mismatch with imap-hibernate and mixed POP3/IMAP access
Hello Aki, Timo, according to git this fix should be in 2.2.27, which I'm running, so I guess this isn't it or something else is missing. See: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=859700 Regards, Christian On Thu, 6 Apr 2017 15:37:33 +0900 Christian Balzer wrote:> Hello, > > On Thu, 6 Apr 2017 09:24:23 +0300 Aki Tuomi wrote: > > > On 06.04.2017 07:02, Christian Balzer wrote: > > > > > > Hello, > > > > > > this is on Debian Jessie box, dovecot 2.2.27 from backports, > > > imap-hibernate obviously enabled. > > > > > > I've been seeing a few of these since starting this cluster (see previous > > > mail), they all follow the same pattern, a user who accesses their mailbox > > > with both POP3 and IMAP deletes mails with POP3 and the IMAP > > > (imap-hibernate really) is getting confused and upset about this: > > > > > > --- > > > > > > Apr 6 09:55:49 mbx11 dovecot: imap-login: Login: user=<redacted at gol.com>, method=PLAIN, rip=xxx.xxx.x.46, lip=xxx.xxx.x.113, mpid=951561, secured, session=<2jBV+HRM1Pbc9w8u> > > > Apr 6 10:01:06 mbx11 dovecot: pop3-login: Login: user=<redacted at gol.com>, method=PLAIN, rip=xxx.xxx.x.46, lip=xxx.xxx.x.41, mpid=35447, secured, session=<uZw7C3VM9vfc9w8u> > > > Apr 6 10:01:07 mbx11 dovecot: pop3(redacted at gol.com): Disconnected: Logged out top=0/0, retr=0/0, del=1/1, size=20674 session=<uZw7C3VM9vfc9w8u> > > > Apr 6 10:01:07 mbx11 dovecot: imap(redacted at gol.com): Error: imap-master: Failed to import client state: Message count mismatch after handling expunges (0 != 1) > > > Apr 6 10:01:07 mbx11 dovecot: imap(redacted at gol.com): Client state initialization failed in=0 out=0 head=<0> del=<0> exp=<0> trash=<0> session=<2jBV+HRM1Pbc9w8u> > > > Apr 6 10:01:15 mbx11 dovecot: imap-login: Login: user=<redacted at gol.com>, method=PLAIN, rip=xxx.xxx.x.46, lip=xxx.xxx.x.113, mpid=993303, secured, session=<6QC6C3VMF/jc9w8u> > > > Apr 6 10:07:42 mbx11 dovecot: imap-hibernate(redacted at gol.com): Connection closed in=85 out=1066 head=<0> del=<0> exp=<0> trash=<0> session=<6QC6C3VMF/jc9w8u> > > > > > > --- > > > > > > Didn't see these errors before introducing imap-hibernate, but then again > > > this _could_ be something introduced between 2.2.13 (previous generation > > > of servers) and .27, but I highly doubt it. > > > > > > My reading of the log is that the original IMAP session > > > (<2jBV+HRM1Pbc9w8u>) fell over and terminated, resulting in the client to > > > start up a new session. > > > If so and with no false data/state transmitted to the client it would be > > > not ideal, but not a critical problem either. > > > > > > Would be delighted if Aki or Timo could comment on this. > > > > > > > > > If you need any further data, let me know. > > > > > > Christian > > > > Hi! > > > > You could try updating to 2.2.28, if possible.
