Well, some applications in 11.3 accidentally crash. But most of them does not want to crash in a moment I am debugging them in the gdb, I searched in the documentation and found a simple solution. Collect cores: 1. Set SOFTCORELIMIT in /etc/sysconfig/ulimit to "unlimited" or do this just now by: ulimit -c unlimited 2. mkdir /cores ; chmod +t /cores ; chmod og+rw /cores 3. Add a line to /etc/sysctl.conf: kernel.core_pattern = /cores/%e-%t-%u.core or do this just now by: echo "/cores/%e-%t-%u.core" >/proc/sys/kernel/core_pattern Core files will be stacked to /cores and ordered by application name and time and will never overwrite. You can easily find a most crashing application there. Install debuginfo: gdb often complains on missing debuginfo packages. You can easily install all of them by copy and paste it to the console input of following command: eval zypper install $(sed -n 's/Try: zypper install//p') Well, you can do the same using the gdb log file and then reading it: eval zypper install $(sed -n 's/Try: zypper install//p' <gdb.log) And in gdb use: Nebo v gdb set logging file gdb.log set logging file on set pagination off attach {pid of application I want to debug} detach attach {pid of another application I want to debug} Well, and if you have a core file, do the final well known: bt or thread apply all bt Notes: Don't forget to check the backtrace in Bugzilla and submit unique crashes. If it is an accidental crash, it makes sense to submit the backtrace to the upstream Bugzilla, if the crash makes a big problem to use particular application or if you suspect that it is openSUSE specific, submit it to the Novell Bugzilla as well. Well, if the core comes from npviewer, feel free to run: rm /cores/npviewer* It does not make sense to report them anywhere. All these crashes I have seen were triggered by Adobe Flash or Adobe Reader and I have no chance to fix them. Wanted: An easy manual how to be always ready for kernel crash dumps. -- Best Regards / S pozdravem, Stanislav Brabec software developer --------------------------------------------------------------------- SUSE LINUX, s. r. o. e-mail: sbrabec@suse.cz Lihovarská 1060/12 tel: +420 284 028 966, +49 911 740538747 190 00 Praha 9 fax: +420 284 028 951 Czech Republic http://www.suse.cz/ -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
