Hi,
I am getting the Out of memory.
To circumvent the problem, I have commented the call to "out_of_memory(),
and replaced "goto restart" with "goto nopage".
At "nopage:" lable I have added a call to "schedule()" and then "return
NULL" after "schedule()".
Bad idea - in the configuration you have, the system may need the
out-of-memory killer to free up memory, otherwise the system can
deadlock due to all memory being exhausted.
I tried the modified kernel with a test application, the test application is
mallocing memory in a loop. Unlike as expected the process gets killed. On
second run of the same application I am getting the page allocation failure
as expected but subsequently the system hangs.
I am attaching the test application and the log herewith.
I am getting this exception with kernel 2.6.13. With kernel
2.4.19-rmka7-pxa1 there was no problem.
Why its so? What can I do to alleviate the OOM problem?
Please see Documentation/vm/overcommit-accounting in the kernel source tree.
