Hi.
Just got this error (1.1.rc4), is it something to worry about?
Corrupted index cache file /.../Maildir/.Sent/dovecot.index.cache: used_file_size too large
This gets automatically fixed and it's invisible to users, but it shouldn't happen of course.
What OS and filesystem are you using? Anything special like NFS/clusterfs/etc.? Could you post your dovecot -n output?
Can you reproduce this using imaptest stress testing? http://imapwiki.org/ImapTest
This is a shared mailbox with concurrent access. In general, can that usage pattern mess up the index? I am guessing "no", which is why I worry slightly about the warning.
Shared mailboxes should be no different from a single user using multiple connections to the same mailbox.
