Hi Barry,
this means that `context` must have been null, which cannot really be. You
cannot by chance upgrade to a later version, preferably 2.3.2? There were
some things that were fixed in ActorCell within the past two release
cycles, but I do not recall this particular problem (which basically means
that terminate() is called twice—or your program is doing something truly
despicable ;-) ).
Regards,
Roland
