Subject Re: Synapse with IBM JDK 1.5 over httpcore-nio
Date Sat, 26 Sep 2009 01:48:58 GMT
Oleg, I am trying to reproduce this, but it is not consistent so I was not
been able to get the exact logs, even though I got it couple of times when I
was trying it yesterday :-(

Will get back to you once I get some useful data.

Thanks a lot for your help.

Thanks,
Ruwan
