Dear experts
I run ltp-full-20170516 on my server . My kernel is RT kernel 4.4.70-rt83.
I use " ./runltp " to run the test suite, and when run test case oom01, it will cause server hang-up.
It could be repeat .
But when I run oom01 on normal kernel (non-RT), it will run smoothly.
I do not know if LTP is not suitable for real-time kernel or there is a BUG?!
Following is the kernel log when server hang-up:
