Hi, I'm running two sendmail processes, MailScanner, RAZOR, Spam Assassin on a MX box, running FreeBSD 4.7. /var/log/maillog has the following entry: Dec 10 08:37:06 mx3 sendmail[25140]: File descriptors missing on startup: stdin, stdout, stderr; Bad file descriptor MailScanner is also randomly dying. The two problems seem to be one and the same. I put the following in /etc/sysctl.conf: kern.maxfiles=65536 # System-wide limit kern.maxfilesperproc=32768 # Per-process limit and ulimit -n 32768 in my sendmail and MailScanner startup scripts. I then rebooted the box and all seemed ok. 5-6 hours later the problem is back. So it look like the file descriptors are being used up? Note that this does not happen on every email, but often enough. lsof does not show anything suspicious. I've looked high and low over the web, but found no definite answer to this problem.
