I'm not quite sure how to debug this. When dbmail-imapd is in this state, new connections take upwards of a minute before they get a response from the imap server. Stopping dbmail-imapd and restarting kills the zombie and everything goes back to normal. ====================================================================== ---------------------------------------------------------------------- bjohnson - 01-Nov-06 21:48 ---------------------------------------------------------------------- Interesting. I have another server running 2.0.10 on Fedora Core 1 and the dbmail-lmtpd has zombies. Any hints on where to start debugging this? # ps aux | grep Z USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1107 0.0 0.0 0 0 ?
