yes, in times of mounting deficits, that would be a troubling message!
in my experience, it usually indicates that the final evaluation step
did not succeed, typically because the TADM evaluate binary crashed.

i have recently made a number of improvements in speed and robustness
to the MaxEnt experimentation support in the LOGON tree.  for those of
you running non-vanilla experiments, i recommend you move to the LOGON
development `trunk'.  see LogonSvn on the wiki for instructions.
