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?
Thanks,
Jonathan
