Hammer Core Dumped on DragonFly v2.13.0.154.g481b38-DEVELOPMENT

[Siju George]

Hi,

Hammer Core Dumped on My v2.13.0.154.g481b38-DEVELOPMENT.

I have uploaded the core dump to leaf:/home/sgeorge/crash/Coredump20111114.tbz
Files are

Coredump20111114/
Coredump20111114/kern.2
Coredump20111114/info.2
Coredump20111114/vmcore.2
Coredump20111114/bounds
Coredump20111114/core.txt.2


However the system is up and running after a reboot.

Would this have affected the file system?

Should I try a latest src or wait till I hear from you?

This kernel did run fine for many days though
