With Cyrus imapd, especially within the Kolab Server we saw file corruptions which could be related to mmap problems. It occurrs rarely enough that we do not have a testcase. Details at kolab/issue840. So I would welcome patches for older kernels and referable information on how long this bug has been in there.
