Issue when lbsram is full

When lbsram is full it looks like we get an error which end up by some inheritance not being done. And having the DarRefCopyStack not having the _process_id attribute. which is a very weird error.

But this come probably from having this initialized in a thread and the error happening in a 'init' probably not completed being hidden. To be checked.

This happen on ID16B on September 2023 and the only solution we had was to clean the lbsram by rsync and relaunching it.
