ACK, ACK, ACK. I was just surprised it started! I have noticed this behaviour a long time agoe on FreeBSD, I didn't know it's spread over to Linux in such a way already. How many cpus/cores/threads does your server have? @devs: Has anyone observed this kind of behaviour on a system where there is a usable DTrace? -- i Igor Galić Tel: +43 (0) 664 886 22 883 Mail: [email protected] URL: http://brainsware.org/ GPG: 6880 4155 74BD FD7C B515 2EA5 4B1D 9E08 A097 C9AE
