SubjectRe: Memory leak in 2.6.11-rc1?
I am running 2.6.11-rc2+ fix for the pipe related leak by Linus. I am 
currently running a QT+KDE compile with distcc on two machines. I am
running these machines for around 11 hours now and swap seems to be
growing steadily on the -rc2 box - it went to ~260kb after 10hrs, after
which I ran swapoff. Now after couple hours it is at 40kb. The other
machine is Knoppix 2.4.26 kernel with lesser memory and it hasn't run
into swap at all.

On the -rc2 machine, however, I don't feel anything is sluggish yet. But
I think if I leave it running long enough it might run out of memory.

I don't know if this is perfectly normal given the differences between
2.4.x and 2.6.x VM. I will keep it running and under load for a while
and report any interesting stuff.

Here is /proc/meminfo on the rc2 box as of now -
