Distributed XA transaction fails to start

I’ve the same problem only when I execute my flow step by step. If I don’t trace into this step there is no problem.

Same here… I’m getting this issue… and then after that message appears, the server crashes! … I think its a broker related issue because when we turned the broker service off it doesnt crash. But I just want to know what is wrong for future reference and to fix this issue.

Regards
