Hello, running CyrusIMAP 2.2.8 on Debian Sarge, with a murder of 2 frontends & 3 backends, (4 & 4) at the end.
I have to deal with increasing charge of by now 500 users that will grow up to 100 000. All mailboxes exist, for a 65Mb mailboxes.db on mupdate 1- Mupdate slows down informing Frontends of changes on backends : on which parameters do I have to play with ? 2- When updating mailboxes ACLs to relfect LDAP changes with Perl through Cyrus::IMAP::Admin, got the following error on the backend : mupdate-client: getaddrinfo (mupdateserver (null)) failed: Temporary failure in name resolution while the mupdate was dealing with reservations from backends. I modified the mupdate master process in cyrus.conf for mupdate processes with a prefork=50. I'd need a piece of advice for using correct values for mupdate parameters in imapd.conf 3- Need also help on correct values for configuring BDB cache a 65Mb mailboxes.db (Berkeley 3.2) on each type of murder server, as I found very poor docs on that subject. If any other point to look at for fine tuning, please tell me. Thanks in advance for your help (Had no time for real tests under heavy load so can't test on production platform !!!)
