Hey Craig thank you very much for your response.

I tried a truncate without the cascade option. After that I tried it with the cascade option. The session just hanged indefinitely at that point. There was no rollback and I was testing on an empty table.
Replication was in a ready state on both nodes and both DDL and DML was replicating.
0.9.2.0 BDR
When you say restarting the nodes. I did restart postgres and this didn't help.
