I had the same thing happen to me yesterday:
Sep 29 05:09:30 kite kernel: Unable to load interpreter
Sep 29 05:09:33 kite last message repeated 2 times
In /var/log/messages, the above lines are followed by 86506 copies of the
\0 character and then the log resumes with normal messages.
I see that unable to load interpretor is in binfmt_elf.c. I'm running
linux 2.0.21 on an all-elf debian system.
At 5:00 each morning, my system sends out a slew of email messages (about
300 each day), and that was probably still going on when the above error
showed up so the system was under a bit of load at the time..
