-The reason for this bus error is that the pytorch program tries to write the file "checkpoint.pth.tar" to the home directory but the home directory cannot be accessed because of an expired kerberos ticket.
+The reason for this bus error is that the pytorch program tries to write the file "checkpoint.pth.tar" to the home directory but the home directory cannot be accessed because of the kerberos ticket expired.
+You can check the status of your current kerberos ticket with "klist".
+<code>
+beckmanf@breakout:~$ klist
+Ticket cache: FILE:/tmp/krb5cc_12487_ssddef
+Default principal: beckmanf@RZ.HS-AUGSBURG.DE
+Valid starting       Expires              Service principal

+The kerberos ticket lifetime 10h and the renew time is 24h. So after 18:28:43 you cannot access your home directory anymore. You can apply for a new ticket with longer lifetime and a longer renew time with "kinit".
+<code>
+beckmanf@breakout:~$ kinit -l 2d -r 7d
+Password for beckmanf@RZ.HS-AUGSBURG.DE:

+This applies for ticket lifetime of 2 days and a renew time of 7 days. You can check the result with klist again.
