So you're using AIX? Do you also happen to use NFS? Can you reproduce this error by running imaptest for a while? http://imapwiki.org/ImapTest
No NFS here. The filesystem is called GPFS. It is a clustered FS.
Ah, that probably explains it. Can multiple different servers modify the same mailbox?
Yes. I have N+1 machines that access the same filesystem and it looks local to both machines.
Cache file is the part of Dovecot that demands the most from the OS/filesystem. The most difficult part is probably that it writes to the file without locking. It first reserves a space and then starts writing there. Multiple processes can write to the same file at the same time. This should probably be changed at some point, since it could just buffer more data to memory and then lock, write, unlock. That would also make the code simpler, since it can currently leave holes to the file because it has to guess initially how much space to reserve..
Ok. Should I disable Cache file or what would be the best fix?
