Hi. I've got a line like the following in my cyrus.conf files: mupdatepush cmd="/usr/lib/cyrus-imapd/ctl_mboxlist -C /etc/imapd.conf.i01.master -m" It is meant to synchronize the backend mailbox list with the mupdate master upon startup. Sometimes, it takes horribly long to complete: one to three hours with 600000 records in the mailboxes list. (Sometimes it takes a lot less time, something like 9 seconds). There are 24 nodes in my murder. Could this create locking problems on the mupdate master? --Janne -- Janne Peltonen <janne.peltonen@xxxxxxxxxxx> ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
