+====
+As of the {product-title} versions 4.8.35, 4.9.26, 4.10.6, the {product-title} default per-pod pid limit is `4096`. If you want to enable this PID limit, you must upgrade your {product-title} clusters to these versions or later. {product-title} clusters with prior versions use a default PID limit of `1024`.
+
+You cannot configure the per-pod PID limit on any {product-title} cluster.
