I have 10 machines on dual core-i7 (amd64) with 16G RAM running 9.10. They're randomly rebooting after months of stability with absolutely no messages in the logs so I've assumed I've got a kernel panic and installed linux-crashdump. I get no output in /var/crash, other than once I had a log file that said it failed attempting to save a crash. The log file disappeared so I don't have the exact message. I also don't have console access so I'm not sure if I'm getting an error about reserved memory that's not in a log file. The machines are in a remote facility.
The wiki page (https://wiki.ubuntu.com/KernelTeam/CrashdumpRecipe) says 'In Karmic all that is needed is to install the "linux-crashdump" package. After a reboot the system should be able to catch crash dumps automatically and provide them to apport.'. This does not appear to be true. The machines also have no direct internet access so apport does not appear to work correctly, even with http_proxy set. I don't get any crash dumps when simulating/forcing a crash (echo c > /proc/sysrq-trigger) either. However, I have a test VM with only 2GB of RAM and I do see dumps when I force a crash. I'm wondering if the large memory (16GB) may have something to do with this. The only other thing I have set differently between the VM and the remote machines is kernel.panic=5 in sysctl. I was thinking that may be forcing a reboot before the dump can complete? I'm really not wanting to eliminate that setting though because I *need* those machines to come back if they panic due to them being offsite. -- linux-crashdump fails to record crash; reports memory not reserved https://bugs.launchpad.net/bugs/321970 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
