This time, the kernel had a swappartition which was about 200MB. As the swap-partition was fully used, the kernel killed all processes of knode. Nearly 50% of RAM had been used for buffers at this moment. Why is there so much memory used for buffers? I know I repeat it, but please: Fix the VM-management in kernel 2.4.x. It's unusable. Believe me! As comparison: kernel 2.2.19 didn't need nearly any swap for the same operation! Please consider that I'm using 512 MB of RAM. This should, or better: must be enough to do the rsync-operation nearly without any swapping - kernel 2.2.19 does it! The performance of kernel 2.4.18pre1 is very poor, which is no surprise, because the machine swaps nearly nonstop.
