Need help with error message

I recently startet to use CP 2.1 and my pipeline runs locally nicely. CP 2.1 is also installed on our inhouse cluster but running the pipline there was not of success. No results have been produced. All jobs failed. The log contains the following error-message:

Uncaught exception in Traceback (most recent call last): File "/sw/apps/cellprofiler/2.1.1/", line 249, in main run_pipeline_headless(options, args) File "/sw/apps/cellprofiler/2.1.1/", line 828, in run_pipeline_headless pipeline.save_measurements(args[0], measurements) File "/lustre/sw/apps/cellprofiler/2.1.1/cellprofiler/", line 1286, in save_measurements add_all_measurements(handles, measurements) File "/lustre/sw/apps/cellprofiler/2.1.1/cellprofiler/", line 291, in add_all_measurements max_image_number = np.max(image_numbers) File "/sw/apps/python/current/lib/python2.7/site-packages/numpy/core/", line 2259, in amax out=out, keepdims=keepdims) File "/sw/apps/python/current/lib/python2.7/site-packages/numpy/core/", line 26, in _amax return umr_maximum(a, axis, None, out, keepdims) ValueError: zero-size array to reduction operation maximum which has no identity

Can anybody help troubleshooting?
