Task failed with exit code minus 1

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 slave.

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.
