Hello Tom,
We'd need to look at the relevant sections of the supelog, workerlog, and joblog to get a better understanding of the issue. Namely, we'd want excerpts of supelog (from the supervisor) and workerlog (from the worker in question) from around the time that this issue was encountered. We'd also like the joblog folder (found also on the supe machine) of the job that was bumped off from the worker at the time.
Would you zip and email those to support@pipelinefx.com, mentioning this forum thread? If you need assistance in locating the log files, let us know.
Thanks!
