Milter-greylist nor clamd are not able to fork on kant. What makes you think that they're unable to fork? Because clamd uses multithread and multitask features. When mimedefang send a mail to clamd socket, clamd forks itself to analyze this mail. On kant, clamd is not able to fork, or maybe is able to fork but cannot analyze any mail, and mimedefang aborts with a busy timeout. If I replace clamd by clamscan, mimedefang works (but alayze process take a very long time). When I try to replace clamscan by clamdscan that uses clamd, mimedefang hangs after a very short number of analyzes. Maybe clamd implementation is broken with libc6 2.5. The only significative difference for me is the libc release. Root kant:[~] dpkg-query -l libc6 ... ii libc6 2.5-9 GNU C Library: Shared libraries rayleigh:[~] dpkg-query -l libc6 ... ii libc6 2.3.6.ds1-13 GNU C Library: Shared libraries 2.5 gives you NPTL, which means that threaded programs can have real threads instead of forking. If you do a ps -eLf on a glibc2.5 system with numerous clamdscan processes going, you will hopefully see multiple clamd lines (same PID, different LWP number). If you don't, maybe there's an issue with libpthread. I see some clamd threads, but even with some threads, clamd cannot analyze inbound mails. I have another question about threads. On a U80, with four UltraSparc processors, are two threads of one process limited to ressources given by one processor, or can they be shared on two processors (like regular process) ? Strange. Problem solved when I have rebooted my U80... I have seen a bind9 instability too that was solved by the same action...

Would this be an expected result or have I made a mess of it. That entirely depends on what you've done and how you've done it. As the pages contain no methodology it's impossible to give anything other than generalities. Doing benchmarking properly is difficult; I tend to start by reading the section of Hennessey and Patterson relevant to what I want to measure.

Hi folks, in case of U60 I can only confirm what Steve said, U60 is a great box for installing Debian. To connect a normal PC-Style monitor to your system you might want to consider a Raritan Sun VGA-Converter 13W3- D-Sub 15. Saves lots of headaches (though you won't get it for free). It is called Adapter:1395. Hope this helps, take care Dieter -Ursprüngliche Nachricht- Von:Steve Pacenka [mailto:[EMAIL PROTECTED] Gesendet: Do 14.06.2007 02:59 An: debian-sparc@lists.debian.org Cc: Betreff:Re: [sun]debian On Wednesday 06 June 2007 05:23, Eric Rapilly wrote: I have some questions, may be you wille be able to answer me.
