[nos-bbs] JNOS Crash

[Jerome Schatten]

Only a guess.... but if it were I, I would look on the pi setup to see 
where libc.so.6 lived, and then look and see if it's
in the same place in the system that's crashing. If not, on the crashing 
machine, stick  a copy of libc.so.6 into the same directory as it is on 
the pi machine, and see what happens.
Like I say, just a guess... Good luck.
