Hi,
a while back I had some issues firing the DEDirector from a number
of threads and the answer was to wrap the firing in a change request. At
the time Edward Lee explained that this was necessary because we were
using fireAt rather than fireAtCurrentTime. He also made a few changes to
the DEDirector to support the change request mechanism.
>From this, I changed our code so that the asynchronous fireAt() calls are
wrapped in a change request and the fireAtCurrentTime() ones are not. That
now works pretty well ... but I am occasionally seeing problems with
fireAtCurrentTime(). See the following stack trace:

Does anyone have any idea why this can happen and what I can do it fix it.
Would wrapping it in a change request help? It seems a heavyweight
solution - I don't care when the DEDirector fires .. I just want to
trigger a firing at the next possible opportunity.
Thanks,
Ian
ps: Edward, we're still working on what we talked about at the end of
November. Things here move really slowly in December because of the year
end accounting but that's all done now so we should be able to move ahead
in the next few weeks.
