My workbench run successfully but when I enable parallel processing on a custom transformer, and 'FME has stopped working' error/APPCRASH occurs.

 

I have tried:

  1. using only one group to process to rule out having too many parallel processes,
  2. I have tried setting to minimum, moderate processing.
  3. I have tried publishing to FME server and running.

 

All fail as long as parallel processing is enabled on the custom transformer. Does anyone know the solution for this?

Could be a number of things, you will need to try and pin point the place where the crash is happening. The log file should help a little here.

Something to note, when parallel processing like this FME first has to write out the data to temp. The data is then read by a new process from the temp location. Is your system funning low of space? This could effect the process.
