Re: [xmlblaster] Connection transition DEAD -> DEAD



Michele,
I'm now using the latest from cvs. I managed to reproduce the error two times out of 30 or so, and don't know what I did differently to make it appear. If it happens again and I can reproduce it I'll be sure to send you the complete logs.


Thanks,
Aaron

Hi Aaron,
we were invainly trying to reproduce the error (with the new cvs code).

Are you able to reproduce it ? In such a case you could send the complete log (with -trace true -call true) either Marcel or me (or both).

Greetings
Michele
