Dear list,
we're using dovecot 2.1.15 (debian binary package). The following error can be found in the mail log files:

The same problem was reported by Ralf Hildebrandt one year ago. The bug should be fixed with revision 3599790da3d7 but it seems to be there again.
Input/output errors of the file system are improbable because all files are accessible and can be read with cat and less.
Any ideas?
Best regards, Gordon
