#
# This test validates that transactions monitor dies if UDF fails.
#
# Test:
# 0. This test requires two servers
# 1. Start group in single primary mode.
# Server1 will be primary and server 2 secondary.
# 2. Stop the applier thread on server2.
# 3. Start a primary change on server1 and block the operation at validation.
# 4. Wait for the THD_transaction_monitor thread to start and unblock the operation.
# 5. Allow the primary change operation to continue.
# 6. Check the monitor thread exited.
# 7. Cleanup
