this is indeed very strange. I hope you have a Genode version where
there is no Slab-Backend allocator, have a look at
'include/util/allocator_fap.h" in the dde_rump repository, there should
only be a PERR message with the slab warning left. Otherwise, our
current "Rump kernels" version is not up-to-date and they have fixed
some serious memory issues there (especially with the paging daemon).
If you have a current Genode version, then there is something wrong with
the memory accounting, which leads Rump to think it has got more memory
than the Genode quota actually suggests.
