The worker process (calibre-parallel) often fails when BOINC is running on GPU in background.
The pipe connection seems to be instable. There are a lot of error messages like "... pipe closed unexpected" or "Something strange happened. The worker process was aborted without an exception."
These error occur when:
BOINC only uses the GPU (AMD Readon HD 6570) for OpenCL calculations. All CPU cores are free. CPU load < 4%
When stopping BOINC or switching GPU calculation to CPU calculation mode the errors disappear.
The errors also occur when connecting to Calibre over LAN (SSH + X11) from another computer. Calibre runs on desktop server but resulting GUI is displayed over network on client laptop computer. This configuration works fine, but there are often these strange errors with broken pipes.
Is there a way to make Calibre's pipe connections more stable?
