The registerUnitConfig remote methode can only throw an InterruptedException if the the remote tasks (register unit config) takes to long right? At least a shutdown was not initialized. So maybe this is issue is caused as well by the deadlock reported in openbase/bco.dal#104?

[DivineThreepwood]

Seems to be solved with commit openbase/jul@40ee3a2 and openbase/bco.dal@ee83a7a Let's keep this issue at least for one week in the review section so it can be reopen if it occurs again.

Fix confirmed.
