We managed to fix this problem. A colleague found out that the incredible amount of spoofed DNS requests that we send causes the cached hostroutes to eat up all KVM. We now expire that routes earlier, and both machines are running rock-solid; each of them handles 60k+ spoofed DNS requests/sec without a glitch - probably they could take more, but we can't measure that anymore :-) "FreeBSD: The Power to Serve!" regards, le -- Lukas Ertl eMail: l.ertl_at_univie.ac.at UNIX-Systemadministrator Tel.: (+43 1) 4277-14073 Zentraler Informatikdienst (ZID) Fax.: (+43 1) 4277-9140 der Universität Wien http://mailbox.univie.ac.at/~le/Received on Fri Jul 11 2003 - 11:58:12 UTC
