+- Known bugs and limitations on AKS CoCo
+  * The total amount of container image layers per pod is restricted to 32.
+  * Container memory limits are wrongly applied. Workaround: only use memory requests.
+  * Directories with a large number of files may cause applications to hang. Workarounds:
+    - During image build, try to keep directories under 4096 bytes (~200 files).
+    - At runtime, `touch` a file in the affected directory to force it into the overlayfs workdir.
