Issue
Performing a long-running build with a detached step will return a "Task failed with exit code -1" while running shell commands such as sleep on a FreeBSD builder agent.

Resolution
During the installation of a JDK. The FreeBSD package system tells you to add these lines to the system `/etc/fstab file:
fdesc /dev/fd fdescfs rw 0 0 proc /proc procfs rw 0 0
This above step was more than likely skipped during initial JDK installation. To fix the problem, add the above lines to the fstab and then mount them with:
mount -a -v
Rerun a build to confirm that the problem is solved.
This problem is not noticed on other operating systems because there is no need to mimic /proc and /dev/fd on systems that run on a linux based kernel.
