From c4023a9302c81f04865646d765caf58ccf556cae Mon Sep 17 00:00:00 2001 From: Daniel J Walsh Date: Mon, 6 Jul 2020 14:14:48 -0400 Subject: Pids-limit should only be set if the user set it Currently we are sending over pids-limits from the user even if they never modified the defaults. The pids limit should be set at the server side unless modified by the user. This issue has led to failures on systems that were running with cgroups V1.
