Description
When testing head of octopus branch, WebAppMgr appears to be freezing while causing excessive swapping and cpu usage.
This is reproducible either immediately after boot or after launching one or several apps with no obvious signs of causing it. The following excerpt seems to be mostly occuring when this happens:

This seems to happen only on m3ulcb.
IO operations become extremely slow. journalctl took nearly 20 minutes to complete.
