Hang at "Waiting for all terminals to finish" when run tpcc on mysql

[oleotiger]

When I run oltpbench with ./oltpbenchmark -b tpcc -c config/tpcc_config_mysql.xml --execute=true -s 5 -o outputfile`

The key parameters in configuration file is:

scalefactor=50
terminals=100
works.work.time=300
rate=unlimited

I run oltpbench in a vm with 2core/8G mem/100G SSD disk

From the output log, the benchmark hangs at TERMINATE::Waiting for all terminals to finish .. for about an hour. And still no other output.

What may cause the problem?
