Hello drbd-user,

could someone please explain what this drbd kernel messages are mean,
because after this messages; the /dev/nb0 device could not be used
anymore, only a system reboot (warm boot) helps to resolve from this
stage. Note: drbd was running already 3 month with this configuration.

We are running Red Hat Enterprise 3 AS update 3 with drbd-0.6.6 rebuild
against the smp kernel 2.4.21-20.ELsmp.
