Concurrent task more than 1 throwing error

[sandeepbisht]

When running without using -tp or using it with -tp 1 it works.

But when -tp is set it start throwing this error.

#java -jar target/memcached_benchmark-0.7-runnable.jar load -t mix -s 10.20.2.180:5000 -fc 5000 -ft 2000 -tp 5 -rf b_1_5 -mix-gk 4500 -mix-sk 500
