################################################################################
# This test verifies whether the group_replication works fine when the server
# in a group goes down while there are dml operations running on it.
#
# Test:
# 0. The test requires three servers: M1,M2 and M3.
# 1. Start GR on all the servers.
# 2. CREATE TABLE ON M1 and CREATE a procedure to insert data
#    into the table
# 3. Call the procedure using send operation and sleep for some time.
# 4. Kill and restart the server M1.
# 5. Wait until there are two members in a group
# 6. Start GR on server M1.
# 7. Verify that table t1 has same data across all the members.
# 8. Clean up
