Global transaction ended prematurely

If you ran an onmode -z command to end the global transaction on the coordinator, the transaction might be inconsistently implemented. (For an explanation of how this situation can arise, see Independent actions that result in an error condition.) You can check for an inconsistent transaction by first examining the database server message log for the coordinator. Look for the following error message:
-716 Possible inconsistent transaction. 
Unknown servers are server-name-list.

This message lists all the database servers that were participants. Examine the logical log of each participant. If at least one participant performed a commit and one performed a rollback, the transaction was inconsistently implemented.
