[linuxsh-dev] Memory Leak?

[Masahiro A. <m-...@aa...>]

Hello,

Has anybody seen this kind of behavior with current CVS kernel?

1. repeatedly issuing "free", used memory size keeps increasing
slightly (about 24k byte). Even the HelloWorld wastes similar size of
memory.
2. after launching "bash" and exiting from it, used memory size
increases about 180k byte.
3. following script wastes 10 or more Megabytes, or worse, never finish.

#! /bin/sh
s=`date`
CNT=1000
while [ ${CNT} != 0 ]; do
	CNT=`expr $CNT - 1`
	/bin/true
done

Those occur on both SolutionEngine 7750S and our custom board.

None of those happen with 2.4.5 kernel with patches those I assembled.

I feel that there is some kind of memory leak in current CVS kernel. I'm
trying to figure out why, but I can't think of how to do that yet.

If you have any info, please let me know. I appreciate that.
