In its current design, the replay cache needs to be periodically
expunged so that it does not grow without bound.  To do this, the code
opens a temporary file named krb5_RCxxxxxx, writes the non-expired
entries to the file, then renames it over the existing rcache.

It's possible that lsof is reporting the krb5_RCxxxxxx names when the fd
is actually (after the rename) pointing to the host_1000 file.
