Hi! A couple of weeks ago we started using the Linux TC implementation to shape clients (using HTB) and since then our QoS box started crashing every now and again (talk about inconvenient timing :P). First we suspected hardware, but we replaced the hardware this week and it still keeps crashing. Current machine specs: Celeron 400 MHz 128MB Ram 128MB Compact Flash storage Distribution: stripped down Debian (woody) The machine runs now services whatsoever: ------------< snip <------< snip <------< snip <------------ root@rana:~# netstat -anp Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program nam Active UNIX domain sockets (servers and established) Proto RefCnt Flags Type State I-Node PID/Program name Path ------------< snip <------< snip <------< snip <------------ It has no load whatsoever. The kernel: 2.4.20rc1 with Andrea Arcangeli''s pausing fix applied (I''m running the kernel on several other machines that have much higher load (read: that actually has load), including my own workstation and they''re all very stable. The only other unknown is HTB and so I''m starting to suspect it. I''m using tc from the iproute ss020116-try tarball with the HTB 3.6 patch applied. Now the problem is that I don''t have enough space to log to disk - I''m just logging to console (also logging with kernel log level 8 to console). Each time I get to the machine it is completely dead, and the keyboard leds is flashing continuously. Unfortunately I can''t see whether there is any oopses or last dying messages since I only have serial console on the machine right now (no messages to tty) and each time I didn''t actually check the serial console. I know this isn''t a very useful bug report (will try to get something more useful later on), but I just want to know if somebody else have experienced the same kind of behaviour lately. In anycase, I''ve removed all the rules from the machine and is going to just to QoS on our Cisco routers again until I resolve the problem :P -- Regards Abraham Real programmers don''t write in BASIC. Actually, no programmers write in BASIC after reaching puberty. ___________________________________________________ Abraham vd Merwe [ZR1BBQ] - Frogfoot Networks P.O.
