Hi I have been trying resolve my problem with dovecot for a few days and I dont have idea....
My environment is: dovecot director+5 dovecot guest
dovecot-2.2.36.4 from source Linux 3.16.0-11-amd64 storage via nfs (NetApp)
all works fine but when I update OS from debian 8 (kernel 3.16.x) to debian 9 (kernel 4.9.x ) sometimes I get random in logs: Broken dovecot-uidlist
examle: Error: Broken file /vmail2/po/pollygraf.xxx_pg_pollygraf/Maildir/dovecot-uidlist line 88: Invalid data:
(for random users - sometimes 10 error in day per node, some times more)
File looks ok
But if I change kernel to 3.16.x problem with "Broken file dovecot-uidlist" - not exists if turn to 4.9 or 5.x - problem exists
I have storage via nfs with opions: rw,sec=sys,noexec,noatime,tcp,hard,rsize=65536,wsize=65536,intr,nordirplus,nfsvers=3,tcp,actimeo=120 I tested with "nocto" or without "nocto" - nothing changes ......
nfs options in node: mmap_disable = yes mail_fsync = always
I bet the configuration is correct and I wonder why the problem occurs with other kernels 3.x.x - ok 4.x - not ok
I check and user who have problem did not connect to another node in this time
I dont have idea why problem exists on the kernel 4.x but not in 3.x
