KRB5_RC_IO_UNKNOWN errors are generated by the replay cache code in a
variety of error cases.
It's hard to know exactly what's going wrong from the data available.
The replay cache file is typically something like /var/tmp/host_0, where
"host" is the name of the service and 0 is the uid under which the
service runs. If you could strace the server process while it's failing
and look for failing accesses to a file like that, it might help shed
light on the problem.
One quick thing to check for is whether the VM host is running into a
disk-full situation, as that would manifest as I/O errors.
