No, but I did not run Knoppix for longer time. But what you are experiencing
seems like the standard "opportunistic" memory management: Linux hands out
more memory than there's actually there. When a certain program starts using
a memory page that is not actually there anymore, there is no solution but
to kill of a random program.
There are patches that make Linux behave more correct - but this will
probably restrict your Knoppix usage even more.
Search google for "oom killer", that will probably give more info.
