ltplite test case crashes

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?

Hi!

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...

Hi!

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.
