System hangs during large filetransfers on nfs mount

Hi After mounting a nfts usb drive to my ubuntu box, I have expericed that the system hangs when I try to transfer files larger than 1 GB from the nfts to the ext3 disk. Am unable to do anything other that shutting down the system. Have anyone expericed something similar - or have any ideas for troubleshooting. thx guys irminger

Greetings irminger

Greetings irminger We had a similar problem with Knoppix for awhile. NO idea why. What we did was this...... When it hangs start another write function to that drive ie copy a small file to it. It did not seem to work with a read function but it did seem to "Jog" the bugger into action for our giant files. Hope that wrx4u
