Re: [expert] processes not stopping, but eating 100% cpu time
Hi Todd ! Same thing with vi. Do you have any idea why this happens? I have some database servers with telnet applications running at customers and the problem is very ugly. Currently, I help myself with verynice, but I'm willing to do anything that would help (e.g. installing other ncurses, login, telnet-server, glibc), even recompiling it manually.

I have some database servers with This is an educated guess more than anything. When the application loses the connection to its controlling terminal, it consumes 100% CPU because it is trying to communicate with said controlling terminal. At some point in the past, I was able to reliably repeat the scenario. It seems to be much more difficult now to do it (on my Cooker box, I haven't yet tried it on an 8.x box).

Hey, I know I am anachronistic but I still think ipchains are the king, at least they do what I need done. And to avoid aforementioned problems, I am using the rule: $IPCHAINS -M -S 7200 30 300 That's not to say that I am not using iptables because I am but some habits die real hard. drjung -- J.

[expert] processes not stopping, but eating 100% cpu time
In history, I used Red Hat from 5.2 till 6.2, then I switched over to Mandrake. However, with Mandrake (including 8.2) I sometimes have the effect that an application doesn't get killed, but instead eats 100% of cpu time. This happens to many console based applications, but one way to reproduce it: Install telnet, telnet into your own box, start ntsysv, kill the connection. Open X-Windows, open a console, start ntsysv, close the window by clicking the X button on the window. Other applications are our self-compiled ones, or icpcon (a configuration program for ICP Vortex RAID controllers). This app is statically linked (get it from http://www.vortex.de/ftp/download/rdrnrsrz/linux/icpcon.gz, it run's even when you don't have such a controller installed). The strange thing: this happens mostly with ncurses-based applications, but not with all. mc, the midnight commander, works very well. As I said, those applications where terminated correctly on Red Hat. I'm just puzzled. Any hints? Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

Open a console, su to root, start mc... and then kill the console without having shut down mc. That keeps mc loaded and eating 100% cpu cycles. Tryed under Mandrake 8.2 and Debian Woody... Strange, not on my system. I have a self-compiled KDE 3.0.2, so my console is konsole. The used su is sh-utils-2.0.11-8mdk su calls bash version bash-2.05-16mdk which calls mc with version mc-4.5.55-7mdk mc is linked with libgpm.so.1 = /usr/lib/libgpm.so.1 (0x4001e000) libglib-1.2.so.0 = /usr/lib/libglib-1.2.so.0 (0x40024000) libext2fs.so.2 = /lib/libext2fs.so.2 (0x4004a000) libcom_err.so.2 = /lib/libcom_err.so.2 (0x4006) libc.so.6 = /lib/libc.so.6 (0x40063000) libncurses.so.5 = /lib/libncurses.so.5 (0x4019f000) /lib/ld-linux.so.2 = /lib/ld-linux.so.2 (0x4000) which translates to libgpm1-1.19.6-3mdk libglib1.2-1.2.10-4mdk libext2fs2-1.27-1.1mdk glibc-2.2.4-25.1mdk libncurses5-5.2-23mdk glibc-2.2.4-25.1mdk But on my system this does NOT hang. Can you look at the versions of your RPMs? But others, e.g. icpcon, hang nevertheless. Can it be that something doesn't propagate a needed signal? Something may be - su when you do su as you mentioned - one of xinetd in.telned login when you telnet into your own box Greetings, Holger -- MN-Logistik GmbH http://www.mn-logistik.de Holger Schurig Dieselstr. 18 61191 Rosbach v.d.Höhe Tel: 06003/9141-0Fax: 06003/9141-49 Want to buy your Pack or Services from MandrakeSoft?
