Hi everybody,
I happily use Cyrus IMAPD for quite some time now. Today I had trouble
for the first time: I saw quite some lmtp processes eating all the CPU
(the host had a load of 8.3 at that time - normally it's about 0 - 0.15
as it's still not used as planned). Postfix tried to deliver one more
message to Cyrus (using lmtp over tcp). After restarting cyrus and
requing that message I have one lmtp:
23619 cyrus 25 0 32304 2940 30m R 99.2 0.3 10:18.20 lmtpd
It seems that it will stay. The message contains more headers than text -
I cannot view it very well as I only have the Postfix queue file (which
is not plain text), but I'm quite sure that it contains all the users of
my university's Novell Groupwise server in the To field and was created
using Groupwise (it is an administrative notification that the server
will be shut down), the message is about 50k in size (header + a very,
very short plain text body as far as I see.
lmtpd keeps eating CPU even after postfix drops the connection due to
timeout - after a flush of the queue I have 2 lmtpd processes eating as
much CPU as they get.
postcat -q <QID> or postcat /path/to/queuefile
...it is possible that there's a bug processing a malformed message-id
header or something... anyway, postcat might help you there. It could also
be the sieve script causing the problem if there is one.
I use cyrus-imapd-2.2.10, postfix 2.2 and a sieve script created by Horde
Ingo (I could mail it via PM if that helps, same applies to the queue
file).
Can this be a sieve script issue? A bug? A really bad message that
crashes lmtpd or postfix lmtp? Should I just delete the message and
ignore it or try to dig deeper? Any hints for the latter?
Thanx,
Baltasar
