By now, rump would query its available RAM quota to determine the memory limit minus some RAM reserved for Genode meta-data. This does not work when the VFS rump plugin is used as the available quota belongs to the VFS server. In this case the memlimit should be set by specifing the RAM in the plugin's config, e.g.: ! <vfs> ! <rump fs="ext2fs" ram="64M" writeabl="yes"/> ! </vfs> Fixes #2783.
