I was getting the file ias9i_linux.tar from http://xxx:yyy@download-east.oracle.com/otn/linux/ias/9ias/ias9i_linux.tar (username and password masked to protect the innocent) and decided to take a peek at the contents of that (huge) file, using "tar xfv ias9i_linux.tar". After a few moments, wget segfaulted. I tried to continue the download, using wget -c yada yada yada, and it locks up, becoming an unkillable process (i.e. I had to reboot to get rid of the thing). I could reproduce this with another downloader, who gave me this error:

This seems to be a bug in the kernel, maybe because the file is too big, and VFAT partitions don't like that. I don't have any other operating systems here I can test this on, but I could try installing FreeBSD or downgrading the kernel to 2.2.19 (I'm running 2.4.4) to attempt to trigger this bug again. But, I'd like to ask some knowledgeable person to take a look at that error above to tell me what the hell is going on. I get a similar error when I strace wget (since this one doesn't give any weird errors, just locks up).

Thank you, Carlos.
