Tsung crashes when running with multiple clients.

When running tsung over 3 different client machines, I keep seeing a crash

[root@dhcp-223-187 .tsung]# tsung start
Starting Tsung
"Log directory is: /root/.tsung/log/20150618-2351"
{"Kernel pid terminated",application_controller,"{application_terminated,tsung_controller,shutdown}"}

Crash dump was written to: erl_crash.dump

This happened, because all the 3 clients had different date/time set, or atleast were drifting apart by more than 5-6 seconds.

After setting date/time via ntp I was able to get tsung to run without issues. Remember to run the ntpdate command below on all the client machines.

[root@dhcp-223-187 .tsung]# ntpdate -b time.microsoft.com
19 Jun 04:56:58 ntpdate[7293]: step time server 10.113.60.176 offset 18079.920147 sec


[root@dhcp-223-187 .tsung]# tsung start
