I told about a little different use case:
1. Set in properties file number of servers and drivers (drivers are clients if 
we set --client parameter, please take a look at attachment) e.g:
{noformat}
# Comma-separated list of the hosts to run BenchmarkServers on. 2 nodes on 
local host are enabled by default.
SERVER_HOSTS=localhost,localhost,localhost

# Comma-separated list of the hosts to run BenchmarkDrivers on. 1 node on local 
host is enabled by default.
DRIVER_HOSTS=localhost,localhost
{noformat}

2. bin/benchmark-run-all.sh config/benchmark.properties only in one terminal.

I this case we receive 2 gc files.

I tried reproducing the issue. Below are the steps
1. Run bin/benchmark-run-all.sh config/benchmark.properties in one terminal 
with 2 server hosts
2.Run bin/benchmark-run-all.sh config/benchmark.properties in another terminal 
with 2 server hosts

I have got 4 diff GC log file.

Let me know incase i missed any steps to reproduce it.
