ERROR: CALCULATED VDWA/B FORCES DOES NOT MATCH ENERGY

Hello All,

I'm a new user to NAMD and to programming in general. I tried to execute a
simulation and the same errors are prompted to my 'output' file. The same
error appears whether I'm starting a run for the first time or attempting a
restart. The error is as follows:

"ERROR: CALCULATED VDWA FORCE MAY NOT MATCH ENERGY! POSSIBLE BUG!"
"ERROR: CALCULATED VDWB FORCE MAY NOT MATCH ENERGY! POSSIBLE BUG!"

I can find nothing on this matter. These errors along with the additional
inconsistencies and imprecisions(as shown below) arise a concern. Is this
something I should be worried about? Any help would be appreciated.

Thank You,
Shalton Evans
