# Verify that applier channel received_transaction_set does not grow infinitely
# with holes.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Create a table t1 on a GROUP.
# 2. Execute some transactions on both members. Transactions executed on M1
#    will be on M2 applier channel received_transaction_set, and the dual for
#    M2 transactions.
# 3. Assert check that both members have holes on its applier channel
#    received_transaction_set. The holes are expected and despite them members
#    data is equal.
# 4. Wait for stable set propagation and certification info garbage collection.
#    When that happens, the holes on applier channel will be filled.
# 5. Assert check that both members do not have holes on their applier channel
#    received_transaction_set.
# 6. Clean up.
