Bug Description
In our infrastructure we have a large number of virtual machines running Ubuntu 12.04 (and some that are running 10.04), as well as a couple of CentOS machines.
From time to time they will panic and we'll be left with nothing but a screenshot, which makes for poor debugging. I pushed forward to install linux-crashdump (or crash on CentOS) by default.
Following this documentation on how to enable crash dumps: https:/
The results have been rather sobering. After initiating a panic, the machines shows a back-trace and then just hangs. As the documentation says that the crash-dump can take some time, I've left the machines for several hours in this state with no change.
I've followed several cues, documenting my journey in this ask.ubuntu answer: http://
My final tests were with CentOS, since we only have a handful of machines running CentOS I put a lower priority on testing/
By this token I'm assuming it's not entirely my fault or my systems' fault, but perhaps is more specific to Debian.
s/Debian/Ubuntu/ — I haven't actually tested this on Debian! (I don't have any debian systems.)
