Found null entry in ridbag with rid=#245:-8

When trying to update some vertices we receive the following error message:

com.orientechnologies.orient.core.exception.OSerializationException: Found null entry in ridbag with rid=#245:-8

After that exception the cluster seems broken, no further vertex can be inserted anymore, because of:
com.orientechnologies.orient.server.distributed.task.ODistributedOperationException: quorum of ‘3’ not reached, responses: [node: xxx-odb-orientdb-0 success,concurrent modification record (node xxxodb-orientdb-2): #119:2 database version: 72 transaction version: 71,concurrent modification record (node xxx-odb-orientdb-1): #119:2 database version: 72 transaction version: 71]

What is happening here? And how can I avoid it?
