I have a *very* wild guess, please send the following data: - Do you have a firewall with states enabled? - Do you run your own DNS server (caching nameserver at least)? - If so, which one? - What is the value of concurrencyremote? (/var/qmail/bin/qmail-showctl should tell you) - What is the maxusers value on your kernel? My guess is that some state table gets fscked up, and causes the machine to reboot (not verified, but it is well-known that qmail is *very* aggressive in sending mail out, and each qmail-remote process does some dns lookups, and an external connection attempt...) Note: the above is a wild guess, and might be (and probably is) completely wrong.
