Both are running SMP kernel. ASUS CU4VX 2 1Ghz CPUs 1 GO of RAM 1 Gigabit Ethernet (lge) 1 155Mpbs ATM (Forerunner) (hfa) 1 Built-in 100Mbps ethernet (fxp) Each card has its own IRQ (so I don't think this is an IRQ problem) And both exhibit the same strange behaviour which did not exist when we were running 4.5. The behaviour is as follows. As soon as I try to run a command that outputs a "lot" of data in a short time ( example : netstat (this is the most significative)) from an ssh or a telnet session , the telnet or ssh session just freeze it seems to get dropped by the remote machine (my SMP servers) because after a while the ssh session times out and return to the shell prompt. When I go to the console and I look at the ethernet interface (an lge0) everything seems to be fine. if I do another ssh sessions the machine answers , when I run again netstat -rn as previously the same scenario occurs again. Could anyone tell me what is going on and how to fix this ? I have to add that this behaviour is not present on non SMP machines. -- -- =============================================================== Christophe Prevotaux Email: c.prevotaux@hexanet.fr HEXANET SARL URL: http://www.hexanet.fr/ Z.A.C Les Charmilles Tel: +33 (0)3 26 79 30 05 3 Allée Thierry Sabine Direct: +33 (0)3 26 61 77 72 BP202 Fax: +33 (0)3 26 79 30 06 51686 Reims Cedex 2 FRANCE HEXANET Network Operation Center =============================================================== To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
