Hi Peer & all,

this seems to be a duplicate of "https://forums.suse.com/showthread.php?12909-Memory-not-free-but-no-process-!" and the post there reports that processes won't start, reporting insufficient memory.

Please also see my answer to that thread, which also references a command to "flush" buffers and caches, to test if this is really the cause for not being able to start the process.
