Title:
ARM coredumps zero-length on NFS mount
Status in linux package in Ubuntu:
Invalid
Status in Ubuntu Linaro Evaluation Build:
Invalid
Bug description:
I'm using Ubuntu 1204 for ARM on a beagleboard.
When I generate a coredump when cwd is an nfs mount, the resutling
coredump has zero length. If I generate the same coredump on /tmp, I
get a valid coredump.
I can work around by setting corepattern to point all corefiles at
/tmp, but this is not ideal as my beagleboard has limited storage
available (hence the reason I'm using an NFS mount in the first
place!)
Some details from the system:
