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?
