8390469: LogTest_large_message_vm_Test::TestBody crashes in case of low disc space

[MBaesken]

In case of very low disc space/full disc we run into this crash in the LogTest_large_message_vm_Test gtest.
In case of no (low?) disc space it test LogTest_large_message_vm_Test we run into this crash, this should be avoided.
