It's also possible that there is an IMAP client running wild, making hundreds of connections. The output of "netstat -nt" might show you if there are a lot of connections from a single IP address. If you really need to allow more connections, increase the maxchilds parameter. Beware that you don't overload the server, either with too much I/O or not enough RAM available! :) Andy ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
