Hello,
I have having problems concerning lmtpd crashing when using
Cyrus IMAP version 2.0.14 which do _not_ appear with version
2.0.12. The same (or similar) problem(s) were reported by (an)other
poster(s) to this list a couple of weeks ago but there appears to have
been no discussion since and no resolution? I include details below
for the information of (i) the developers, and (ii), admins who may
be considering upgrading to version 2.0.14. I can provide more
details if necessary.
The problem I have with version 2.0.14 is that lmtpd crashes
relatively often when called by the deliver program. To be a little
more precise, as user cyrus on the imap server, in one test I sent
user "testuser" ten messages in quick succession, by typing the
command
/usr/cyrus/bin/deliver -a testuser -m -- testuser < /tmp/message
ten times, one after another. I found that seven out of the ten
messages _were_ delivered to testuser's Cyrus mailstore but three
of the messages were _lost_ (as if they had disappeared down a
blackhole). In fact, on inspecting /var/log/imapd.log I find three error
messages, corresponding to each of those lost messages. One of
these error messages (with associated text) says:
Jun 19 10:17:22 frosty master[17743]: about to exec
/usr/cyrus/bin/lmtpd
Jun 19 10:17:22 frosty service-lmtpunix[17743]: executed

postman
Jun 19 10:17:26 frosty master[561]: process 17743 exited, signaled
to death by 11
For information: this problem is reproducable on other hardware and
so I fnd it unlikely that it is hardware related!
The machine is running RedHat Linux 7.1.
I compiled and installed Berkeley DB version 3.2.9.
I compiled and installed Cyrus SASL version 1.5.24 with configure
command:
$ CPPFLAGS=-I/usr/local/BerkeleyDB.3.2/include \
LDFLAGS=-L/usr/local/BerkeleyDB.3.2/lib \
./configure --with-plugindir=/usr/local/lib/cyrus-sasl-1.5.24 \
--with-dblib=berkeley --disable-krb4 --disable-gssapi \
--with-rc4 --enable-anon --enable-cram --enable-plain \
--enable-login --with-pam
I compiled and installed Cyrus IMAP 2.0.14 with the configure
command:
$ ./configure --with-dbdir=/usr/local/BerkeleyDB.3.2 \
--with-auth=unix --with-sasl=/usr/local/lib/cyrus-sasl-1.5.24 \
--without-libwrap
Please note that I used the same(*) configuration options with Cyrus
2.0.12, with the same hardware and the same RedHat 7.1 install,
and this lmptd crashing problem was not apparent.
(*) The only difference (apart from the version of cyrus imap itself),
is the "--without-libwrap" option [tcp wrappers] which I chose to use
with 2.0.14 since I was unable to connect to my 2.0.14 server
otherwise (has anyone else noticed a problem here, or is it just
me?).
Thanks,
Nick.
