> * This issue may be related to KAFKA-618
> * To reproduce the issue:
>     1. Download the latest 0.8 branch and apply the attached patch
>     2. In <kafka_home>, execute "./sbt update package"
>     3. In <kafka_home>/system_test, execute "python -B system_test_runner.py" and it will execute testcase_9051
> * The validation output would be as follows:
> validation_status  :
>      Unique messages from consumer on [t001]  :  0
>      Unique messages from consumer on [t002]  :  0
>      . . .
>      Unique messages from consumer on [t019]  :  0
>      Unique messages from consumer on [t020]  :  0
>      Unique messages from producer on [t001]  :  1000
>      Unique messages from producer on [t002]  :  1000
>      . . .
>      Unique messages from producer on [t018]  :  1000
>      Unique messages from producer on [t019]  :  1000
>      Unique messages from producer on [t020]  :  1000
>      Validate for data matched on topic [t001]  :  FAILED
>      Validate for data matched on topic [t002]  :  FAILED
>      . . .
>      Validate for data matched on topic [t019]  :  FAILED
>      Validate for data matched on topic [t020]  :  FAILED
>      Validate for merged log segment checksum in cluster [source]  :  PASSED
> * However, it will work fine if there are only 10 topics
>      In system_test/replication_testsuite/testcase_9051/testcase_9051_properties.json, update the following line to 10 topics:
>       "topic": "t001,t002,t003,t004,t005,t006,t007,t008,t009,t010,t011,t012,t013,t014,t015,t016,t017,t018,t019,t020",
