Subject: RE: Commenting out out_of_memory() function in __alloc_pages()
Date: Mon, 24 Jul 2006 15:14:39 +0530 [thread overview]
Message-ID: <BKEKJNIHLJDCFGDBOHGMGEPDDDAA.abum@aftek.com> (raw)
In-Reply-To: <Pine.LNX.4.64.0607111025320.19812@turbotaz.ourhouse>
Hi,
In the same context I want to know whether kernel 2.6.13 broken?
I got oom, and as per the documentation and code of out_of_memory, all the
processes, which share the same memory address as the process chosen to be
killed, i.e. threads, will be killed. But in my case its not the case
always.
At times the process chosen, "Angelia", is killed will all its threads but
at other times, only some of the threads get killed and the print from oom
killer (function out_of_memory) comes repeatedly but no process is killed.
Why its so?
Anticipation and regards,
Abu.
