I updated one of my production boxes to Cyrus IMAPd 2.4.12 [using Simon's excellent packages]. On my test box / replica I was able to reconstruct all the mailboxes. But [of course] on the production box I have a few mailboxes [important ones, of course] that fail a reconstruct. $ /usr/lib/cyrus-imapd/reconstruct -r user.steve fatal error: failed to mmap new message file $ /usr/lib/cyrus-imapd/reconstruct -r user.barnosky fatal error: failed to mmap new message file Reconstructing other mailboxes is working. Hints / Tips? reconstruct doesn't seem top have a verbose / debug switch. ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
