This bug has been copied from bug #205722 and has been proposed to be backported
to 4.5 z-stream (EUS).
A patch addressing this issue has been included in build 2.6.9-55.0.3.EL.
Can you run the repro_oom test with this kernel:
The patch included in the 4.5.z kernel is not intended to fix the hang seen
running the repro-oom.C program. This patch address a hang issue seen while
running a mix of Database, JVM and fils system backup operations all running at
the same time. The patch has been tested and verified at the customers(Lehman
Bros, Goldman Sachs, etc). Also, this patch has no effect on the system unless
/proc/sys/vm/pagecache is lowered from its default value of 100.
An advisory has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information
