[Pogamut-list] Bots standing around doing nothing

Bots standing around doing nothing

Author: jacob.schrum

I'm running experiments evolving bots, which means that I run several evaluations
in sequence. I always have to kill all the bots, stop the server, restart the server, and
then reintroduce the bots. This seems to work fine for a while, but after several evaluations
I will check in on the match and see that all of the bots are standing still, or if they are
moving they make a move, then stop, then move, then stop. It's like the bots aren't receiving
commands as often as they should.

Looking at the output from the simulation, I think the problem might be related to the following
exception (and surrounding log messages):

_______________________________________________________

Because the exception is being thrown in a thread I didn't create, I don't really know how to deal with this. It seems like I can't possibly catch and deal with it without editing the Pogamut source, which I'd rather not do.

Related to this: If I'm completely restarting the server and all bots in it, then why would the bots have a problem being sluggish? I would think that killing everything and starting over would give me a fresh start and make things run like normal.
