lmtpd should not crash, it is spawned by the Cyrus master process. Exim + Cyrus
runs very stable on our site and many others. Something in the logs? Try adding
local6.all                                   /var/log/cyrus.log
to /etc/syslog.conf and HUP syslogd (see man 5 syslog.conf).


You can check lsof /var/imap/socket/lmtp too.

Assuming that you are using exim 4 >= 4.11 (find out with exim -bV), try the
lmtp transport <http://exim.work.de/exim-html-4.10/doc/html/spec_27.html#CHAP27>
and <ftp://ftp.fu-berlin.de/unix/mail/exim/ChangeLogs/NewStuff-4.11>:

local_delivery:
driver = lmtp
socket = /var/imap/socket/lmtp
batch_max = 20
user = exim
