I think this is the problem. Probably, the master tries to configure the
slave with a zero-sized mailbox. Perhaps the slave doesn't like this.

Do you have the possibility to update the SII data?

If this is not possible, please post the logs with the debug level
set to 1, so we can have a look, which operation causes the error
messages:

rcethercat restart && echo 1 > /sys/ethercat/master0/debug_level
