Summary: Grinder 3.4 - exception "No statistics to report"

Initial Comment:
Hi all,
a simple test script with a single HTTP request runs stable over hours without any issues with Grinder 3.2.
But with Grinder 3.4 the threads run into an exception "No statistics to report".
After this exception the thread dies in the next run with an "Last statistics were not reported" exception.

A trial with a single process and 3 threads results in:
- 08.12.10 11:36:20 - thread 1 run 0: "No statistics to report"
- 08.12.10 11:36:25 - thread 1 run 1: "Last statistics were not reported"
- 08.12.10 11:37:12 - thread 2 run 9: "No statistics to report"
- 08.12.10 11:37:18 - thread 2 run 10: "Last statistics were not reported"
- 08.12.10 11:37:19 - thread 0 run 13: "No statistics to report"
- 08.12.10 11:37:24 - thread 0 run 14: "Last statistics were not reported"

The test was configured to run forever but the load stopped after about 1 minute due to this issues.
Other trials have shown the same behaviour, each of them run into exceptions as listed above.

My Configuration is:
- Grinder 3.4
- JDK 1.6 (1.6.0_20)
- Jython 2.2.1
- Windows 2003 server 64 bit

Another server  (same hardware HP Proliant) with equal configuration shows the same issues.
On my notebook with Windows XP and 32 bit Grinder 3.4 runs stable, but our load generator is the 64 bit Windows 2003 server.

Any help will be appreciated.
Chris
