This is not expected, and bears investigation. It suggests an EINVAL,
EEXIST, EFAULT, EBADF, or EWOULDBLOCK error from one of the I/O
operations performed by fcc_store(), none of which are expected. If
you're building libkrb5, you could try modifying interpret_error() to
pass those error codes through in order to find out which one is happening.
Getting multiple cache entries for a service is normal when multiple
threads or processes initiate contexts to the same (new) service within
a short window.
