Recently I upgraded a moderately busy Cyrus imap from 2.3.x to 2.4.7 I used one of the excellent rpms by Simon Matter and everything went smoothly until the upgrade went live: New mail arrived at once and this triggered an index upgrade, the log contains lines like "Index upgrade: user.xyz (10 -> 12)" Upgrading the index takes some time, in the meantime sendmail delivers more mail, the load soars as index upgrades are run in parallell and sendmail eventually effectively stops processing mail. Later as a number of index upgrades finishes the load drops, sendmail revives and the whole cycle restarts. Running a reconstruct on user.% before allowing in new mail, after the upgrade, seems to be a better and more orderly option than allowing sendmail to do the job? BTW: What happened to the rpms published by Simon Matter? Nothing to be found at http://www.invoca.ch/pub/packages/cyrus-imapd/ recently. -psi ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
