Subject: Combination of pipes and &! leaks file descriptors
Date: Tue, 2 May 2017 16:19:25 +0200 [thread overview]

Hello,
I noticed a file descriptor leak today in a script that was forking
jobs in a loop and ceased to work after 1000 jobs. A (quick, admittedly)
search of the mailing list found nothing relevant. A minimal example is
attached, using `lsof` to demonstrate the problem. I also attached its
output in case there are difficulties reproducing the problem. It is
interesting to see that only the `&!` operator causes the problem, the
`disown` command does not. A pipe needs to be present in the
backgrounded command.
Regards
Jure
