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 > 1008 messages.
Excellent troubleshooting. I'm getting worried that I have a problem and don't know it. Did you get useful error messages (that we can search for, too)?
The man page for cyrus.conf suggests that the default is 256, but that the integer value is optional. So if maxfds does not appear in cyrus.conf at all, is the default 256, or is it unlimited (up to ulimit)? Looks like the former to me. Ick.
Shouldn't the multiappend/append be closing the FD for each stage file and then reopening it later as it needs it?
