| Doug, the problem we see is a file descriptor leak with several

Should be fixed with sys/compat/linux/linux_stats.c version 1.83.
It's fixed in my testing:
/compat/linux/bin/sh
fstat | grep bash
Let me know if there are still some issues. I'm behind in my FreeBSD
mail and working on some other stuff.
Thanks,
Doug A.
