problem using different dovecot versions

[Gonzalo Palacios Goicolea]

Hi All,

I'm new to the list and may be it's a known issue. I have a set of 
servers with RHEL6 and dovecot-2.2.10-1_14.el6.x86_64 and another set of 
servers with RHEL7 and, now, with dovecot-2.2.36-3.el7.x86_64. Both sets 
write to the same NFS.
Since I updated RHEL7 servers (from 2.2.10-8.el7.x86_64) I've problems 
with index files when a RHEL7 dovecot service write to the filesystem of 
a user (the first log line corresponds to RHEL7 and the others to RHEL6):

Due to this issue when the user goes into his webmail, he can not see 
the inbox. If I delete dovecot.* files from the user maildir it gets 
solved, but usually it happens again, so it's not the solution.

Is it any solution for this issue or should I downgrade dovecot to 
2.2.10-8.el7.x86_64 again?

Thanks and best regards
