frontend lmtp connections to mupdate master

[Michael Menge]

Hi,

last night we had a problem with our mupdate master not
working any more, received SIGSEGV, and the next mupdate had an
internal error. See logs below.
I had been under the impression that only changes in the mailbox db
would fail if the mupdate master was not working.

But also mail delivery was failing. The frontend lmtpd tried
to connect to the mupdate master, and didn't use the frontend
mailboxdb.

I was wondering whats the reasoning?
I think the many connections to the mupdate master i have seen,
have not been backend impad processes creating/renaming/deleting
folders but frontend lmtpd processes asking for information which is
available local.

Regards

    Michael Menge
