Hello!
I've been struggling for not few hours with memory leaks on this
machine. I'm running linux 2.6.32-5-686, and the problem is as follows:
Some months ago, I have compiled kernel 2.6.33-2-686 without any issues
in this same machine. This week I have tried compiling GNUzilla Icecat
and the 2.6.35 kernel. But when compiling the kernel, when it is just
starting compiling, all real memory (2GB) fills, and when beginning to
swap, the machine becomes absolutely unresponsive. With Icecat, it
takes 15 minutes before this happens, and today I tried leaving it
working for almost 5 hours, unresponsive, before killing the machine.
I killed the machine almost 10 times this week with high I/O activity.
I've already tried changing vm.swapinness to 60, and
vm.overcommit_memory to 2, but nothing helps. Also disabled the memlock
available for audio applications, but nothing yet. Increased my swap to
10GB, but nothing.
So here goes the output of some commands:
# sysctl -a | grep vm. | sort
