Ohhh...
It seems I am not the only one...
Would you please state your OS, OS Version and JVM.
How often do you get this issue?
Did you manage to find a specific way to reproduce the problem?
In Linux one can use 'lsof -p <pid>' to list the open files. I have
seen extensive 'anon_inode' and 'pipe' descriptors. Please check if
you're having the same issue, or a different one.
Alexey Stashok is helping me pin-point the issue, and it would
probably be very beneficent if we had your input on this.
