Has duplicate Kepler - Bug #5444: Kepler can't run workflow if two instances exist at same timeIn Progress07/29/2011

History

#1 Updated by Jing Tao about 8 years ago

It turns out that i have a another kepler running at my workflow run engine. When i shut it down, the error has gone.

#2 Updated by Christopher Brooks about 8 years ago

I know this is closed, but the problem is that it appears that there
is a bug if two instances of Kepler are running.

I can't reproduce this, but I'm reopening it because the user should be able
to have two instances of Kepler running.

Jing, can you try to reproduce this?
You are running from the Kepler trunk under what platform?

#3 Updated by Derik Barseghian about 8 years ago

I recommend closing as duplicate of: bug#5444 (which could be given a more general title)

#4 Updated by Christopher Brooks about 8 years ago

Good point, bug#5444 includes the same stack trace.
So, I'm closing this one and marking it as a duplicate.
