# This test confirms that when STOP GR and select
# performance_schema.replication_connection_status query is executed
# concurrently, no deadlock happens.
#
# Test:
# 0. The test requires one server.
# 1. Block Stop Group Replication
# 2. Wait for debug sync to be reached and then execute select query
# 3. SIGNAL STOP GR to resume processing
# 4. Confirm Group Replication is stopped
# 5. Cleanup
