Hello everyone,
We use cyrus-imapd-murder as the solution for our website messaging/e-mail service .
We currently have 1.240.088 users split in 3 backend servers using 1 frontend / master server
(both services running on the same server) for a grand total of 3.479.526 mailboxes and it's subfolders.
the servers are used for imap access only. no pop3, no sieve scripts, no news, no shared folders , nothing
else besides imap.
after some days running smoothly I start getting errors on the master/frontend server.
It has happened a few times now..
the errors in question:
cyrus/mupdate[1433]: DBERROR: skiplist recovery /var/lib/imap/mailboxes.db: 141BAD94 should be ADD or DELETE
cyrus/mupdate[1433]: DBERROR: error updating database user.1215407: cyrusdb error
then after some time I start getting these:
cyrus/lmtp[1276]: authentication to remote mupdate server failed: EOF from server
cyrus/lmtp[1276]: couldn't connect to 10.1.5.101: no authentication to server
after a little more time
cyrus/imap[30969]: kick_mupdate: can't connect to target: Connection refused
cyrus/lmtp[2240]: mupdate-client: connection to server closed: end of file reached
cyrus/lmtp[2240]: couldn't connect to 10.1.5.101: no connection to server
then this is what I get when trying to restart cyrus frontend/master
cyrus/ctl_cyrusdb[30607]: recovering cyrus databases
cyrus/ctl_cyrusdb[30607]: DBERROR: skiplist recovery /var/lib/imap/mailboxes.db: 141BAD94 should be ADD or DELETE
cyrus/ctl_cyrusdb[30607]: DBERROR: opening /var/lib/imap/mailboxes.db: cyrusdb error
what I need to do next is completely delete the dbs from the master/frontend and reimport all the mailboxes, but that takes hours.
I came up with a faster solution wich is to configure a dummy backend on the same server the cyrus frontend/master instance
runs which reduces the import time by hours, but thats besides the point.
Below is my frontend/master configuration.
##### cyrus.conf
START { # do not delete this entry! recover cmd="ctl_cyrusdb -r" }
# UNIX sockets start with a slash and are put into /var/lib/imap/sockets SERVICES { # add or remove based on preferences mupdate cmd="mupdate -m" listen=3905 prefork=1 lmtp cmd="lmtpproxyd" listen="lmtp" prefork=0 imap cmd="proxyd" listen="imap" prefork=0 }
EVENTS { # this is required checkpoint cmd="ctl_cyrusdb -c" period=240 }
###### imapd.conf
