Two tesseract commands at the same time blocks each other from finishing

[MoxBe]

Environment

• Tesseract Version: 4.1.0
• Platform: Ubuntu 18.04

Current Behavior:

Running two tesseract commands at the same time blocks each other from finishing.
If I run just one tesseract command it finishes in 2 seconds.
If I run two at the same time it doesn't finish for more then 20 seconds, if I cancel one then the other finishes immediately.

Expected Behavior:

Not to block each other from execution.

Suggested Fix:

Don't know.

Try running it as

OMP_THREAD_LIMIT=1  tesseract  

I have found that while openmp is useful during lstmtraining it slows down lstmeval and tesseract on my system. My workaround has been to use OMP_THREAD_LIMIT=1 before the command.

If you don't plan to do training, you can try to build tesseract with --disable-openmp config option.

OMP_THREAD_LIMIT=1 seems to be the solution, thank you.
