dovecot - Apr 2006 - errors while testing with imaptest

I get lots of these (in error log):

dovecot: Apr 28 14:50:03 Error: IMAP(jenslt): Corrupted index cache file 
/home0/jenslt/.imap/INBOX/dovecot.index.cache: record points outside file

And some of these:
dovecot: Apr 28 14:50:03 Error: IMAP(jenslt): Corrupted index cache file 
/home0/jenslt/.imap/INBOX/dovecot.index.cache: field index too large 
(2037149797 >= 19)

Should I worry or not? (Assuming its not due to me having broken 
imaptest).

This was with command:
imaptest jenslt at xxxx:yyy pass=xxxx clients=40 msgs=300

Local software raid 5 on linux 2.6.16.11 on reiserfs.

Cheers,
Jens

I can also get these quite easily. Haven't bothered to debug it yet
because all cache file errors are transparent to users. The problem has
something to do with a process trying to access a newly created cache
file with old file's offsets.
