Hello, I would like ask for help in despair... I am running complex htb setup to manage two leased lines [1+2MBit] for 500 users. Setup works from few months but in this time I have still awfully problems with stable work. Nowadays there is no week when system hangs two or three times. I tried dozens of setups, patches, recompilations of kernel, iproute and iptables, tricks and still almost without improvement. I tried to find reason but without success. Bellow I mention some observed facts. Maybe someboty could advise or solve problem... When I started with HTB [2.0] [about 200 users on 1Mbit link; Previous it worked on CBQ setup] there wasn't propably [AFAIK] problems with stable work [many days between manual reboot]. From time to time I had some sudden hangs, which become more often later. I changed kernel to 2.4.18 but the reason what I found [or one of the reasons...] whas hardware related [damaged cpu and/or mboard]. I changed completly all hardware and changed kernel to 2.4.18 patched with htb v2. but problem didn't dissapear - frozen system during several days. Most ofen hangs was after 1 or 2 days of stable work but some cases it was 4 or even 7 days. . Then I tried 2.4.18 patched with htb v.3. but situation become hopeless. I found that each changing of htb class parameters [tc class change...] lead to freezing system. Sometimes one sometimes more changing params caused crash. Htb 3 was useless for me and htb 2 was/is also unstable. I also tried htb2 on completly other machine [but with the same Linux distro - PLD], but system crashed almost immediately. Now I am testing 2.4.20-pre7 [with included htb3], system didn't hang immediatelly after changing htb class params but now it works from several hours to one day. Unfortunatelly I didn't have any error messages in logs and on console. ERRATA: Today I have first time to see some logs on console [kernel 2.4.20-pre7], there is something about Oops "Process swapper (pid: 0, stackpage=c0211000)" and a lot of digits. I put screen on location: http://eter.tym.pl/bug2.gif Diging in LARTC archive I found maybe something simmilar problem in post of "Dimitris Zilaskos: [LARTC] tc reliably hangs my system " [http://mailman.ds9a.nl/pipermail/lartc/2002q3/004316.html] but there is not solution for me and despaired I dont know the reason and what to do with it. BTW. If this bug report [http://eter.tym.pl/bug2.gif file] is related more to kernel than to tc/htb please tell me where to send it.
