################################################################################
# This test verifies the impact when a server is crashed during a incomplete
# transaction with savepoints in progress
#
# Test:
# 0. The test requires two servers: M1, M2
# 1. Create a table on M1.
# 2. Start a transaction t1 on M1, and crash the server M1 post savepoint and
# check the status of server on restart.
# 3. Clean up
