Hi,
I tried out the test case ltplite just for fun, and it crashed. The
last part of it was:

Actually, there's a lot more error messages if anyone would care about
it, but I ended up at the login prompt. The system was quite unusable
after this.
Is this the reason why this test case is not in the default list of
test cases?
Does anyone know about this crash?

This looks like the system went out of memory during the filesystem
stress testcase.
Is your /tmp on tmpfs? Because LTP defaults to use /tmp as a playground
to create files...

I've looked at the source code and the TMPDIR is not passed to growfiles
in the runtest file nor is TMPDIR utilized in the growfiles sources so
as far as I can see it seems defaults to current directory which should
be /opt/ltp/....
I would call this a bug.
