BNR had a bug that caused this problem. Paul Lord sent me a patch and it fixed this problem on our pipeline. I assume it will be incorporated in the next release.
Installed the latest exrTrader with BNR4.03 running LW 9.3. A test scene was run through the pipeline, but no image files are written to the output directory. The LWSN log shows an entry for writing the image file, but it also shows OpenEXRSettings master handler failing. I removed the master plugin and it stills fails to write. When running rendering the scene locally, exrTrader successfully writes the images out.

I'm going to try run a LWSN test using a command line batch file to simulate the same command BNR4.03 executes to prove the problem is with BNR4.03. I also see the same problem with previous version of exrTrader and BNR.
