Below are some common error messages and their most likely cause.
GUI connection initialization failed: The batch job was unable to access the graphics card. See Graphic card access section above.
Failed to find task file...: The batch job was unable to access the project directory. See File access section above.
Failed to read frame N for clip...: The batch job was unable to access the footage referenced in the project. See File access section above.
Abnormal exit: This is a general error which indicates that communication with the batch job was unexpectedly lost for some unknown reason. Causes for this could be relatively benign and transitory, such as the network went down or the machine processing the job was rebooted. However, if the problem persists then it may indicate a more serious problem and should be reported in the same manner as if the PFClean application unexpectedly crashes.
