Description Ludek Smid 2007-07-13 12:54:10 UTC 
This bug has been copied from bug #205722 and has been proposed to be backported
to 4.5 z-stream (EUS).
Comment 2 Don Howard 2007-07-31 21:28:02 UTC 
A patch addressing this issue has been included in build 2.6.9-55.0.3.EL.
Comment 5 Larry Woodman 2007-08-29 14:42:35 UTC 
Can you run the repro_oom test with this kernel:

Comment 6 Larry Woodman 2007-08-30 20:51:08 UTC 
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.
