Issue I408 [80,recording,resolved] False "The Data Recording (or Trajectory) File Has Filled Your Disk" message in batch mode. When flying an IOB file in batch mode, where the IOB records data to a file (such as from a workbench user program), you may see this error message in the output: error,Aborting Trajectories: The Data Recording (or Trajectory) File Has Filled Your Disk Either Remove Files From Your Disk to Increase Space or Depress Rerun Button AFTER Starting a Fly'm to Avoid Saving Trajectory Images to Disk Cause: SIMION was attempting to write to a closed file handle and was failing. To reproduce: In the Einzel example, create an einzel.lua workbench program that outputs something: simion.workbench_program() print(123) From batch mode (e.g. "simion.exe --nogui lua"), run this command twice: simion.command("fly --recording-output=out.txt einzel.iob") The second run gives the error message above. Note: also this error can display if SIMION cannot write a temporary trajectory file (e.g. write permissions are disabled on the current directory). The error message is improved in 8.0.4-TEST21. Affects 8.0.3 and likely prior versions. Resolved in 8.0.4-TEST3.
