This is a new one for me: What does this error indicate?
/usr/bin/perl: bad interpreter: Text file busy
There were a couple of disk-intensive processes running at the time, but I've never seen that message before—in fact, this is the first time that I can remember getting an error when trying to run a Perl script. After a few seconds of waiting, I was able to run it, and haven't seen the issue since, but it would be nice to have an explanation for this.
Running Ubuntu 9.04, file system is ext3.
