hi, i've a problem with copying large files from USB-stick on my WL-500G.
First I though this is an usb-driver problem, but then I copied some files to the ram-disk (/tmp) and started
the httpd -h /tmp and tried to wget the file on the remote-machine. Mostly this fails, after 1-5 MB copied the transmission stops. No erro-messages, evan dmesg on the router doesn't show any erro-massage.
The same happens if I scp large files from the router, so it is not an problem of the busybox build in httpd.

I also tried to cat some files  (about 20 mp3 files - approx. 80MB ) to /dev/null after short time this happens:

root@OpenWrt:/mnt# cat * >> /dev/null 
Segmentation fault
root@OpenWrt:/mnt#

now I re-compile busybox with debug information - but I think it could be an Kernel problem, because with the pached ausus-firmware from oleg (http://wl500g.dyndns.org) every thing works fine.
