orientdb: OConcurrentModificationException occurs when insert after delete

OrientDB Version: 3.0.0.SNAPSHOT

Java Version: 1.8

OS: CentOS

When I insert massive edges, I get below exception occasionally.

com.orientechnologies.orient.core.exception.OConcurrentModificationException: Cannot UPDATE the record #156:26159 because the version is not the latest. Probably you are updating an old record or it has been modified by another user (db=v3 your=v2)

In this error log, #156:26159 is an edge. Before this massive edge inserting, I have ran delete command to delete all datas of this edge collection. But I can’t make sure if it was causes by the delete operation. If I create a new edge collection and and re-insert all the datas (without run the delete command), it woks well.
