As I sent to Dale Scheetz earlier,
execve("/d1/eichin/bin/pgp.aout", ["/usr/bin/uustat"], [/* 17 vars */])
= 0
uselib("/lib/ld.so") = -1 ENOEXEC (Exec format error)
(followed by the write() of the message...)
We concluded that it was simply time to switch to a 2.0.x kernel
(after some discussion about which values of "x" were stable...)
