After running this way I found svcgssd opens a file to the kerberos replay cache for every context/cred, eventually reaching ulimit. For a busy cluster with many different client-user pairs that becomes a problem. I am lost in the gss_krb5 code, but suspect that the kerberos code leaks credentials in this configuration.
