I'm using the UW mailutil to transfer mailboxes from UW to Cyrus
(2.3.7). It uses APPEND, specifically multiappend (single APPEND with
multiple messages being appended). Cyrus-imapd handles this multiappend
by creating stage files for each appended message and leaving the file
descriptor open. The problem is that after 240 messages, we run out of
file descriptors and so an open() of the next stage file fails with
EMFILE. I updated /etc/cyrus.conf to make the max fds be 1024 (AFAICT
kernel MAX) which helped somewhat but not for larger mailboxes with >

Shouldn't the multiappend/append be closing the FD for each stage file
and then reopening it later as it needs it?
Already fixed in CVS:
