Hello! I just encountered a rather tricky problem and maybe somebody can benefit from the solution. If one wants to have multiple instances of imapd, for example to support IMAP and IMAPS, or to listen on multiple interfaces (but not all/0.0.0.0, or if one needs different configurations for the separate services), then the recommended way is to just have multiple lines in the SERVICES section. The name of the service (first parameter in the line) is also used in the filename of a lockfile, that needs to be unique for each service, otherwise a deadlock can occur, where multiple services want to hold a lock on the same file. The result will be 1-2 minute long freezes on any connection attempt. This problem was already described by Tuomas Toropainen in this mail: http://lists.andrew.cmu.edu/pipermail/info-cyrus/2007-January/024910.html The tricky part is, that not all names that look distinct really are treated differently by cyrus. Notable example: "imap" and "imap_remote" result in the same lockfile (/var/imapd/socket/imap-0.lock), because the name is truncated at the '_'. The '_' doesn't seem to be illegal per se, because cyrus does not complain and the service runs ok most of the time, i.e. as long as no concurrent connections are created on the 2 interfaces to trigger the race- condition. Maybe other characters cause this problem as well, so if one is unsure about this it would be best to just stick to alphanumeric characters. I have also added this information to the FAQ at http://www.cyrusimap.org/mediawiki/index.php/FAQ HTH, rob ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
