Ruwan Linton commented on SYNAPSE-225:
--------------------------------------

Jeff, 

Adding to Asankha, it is really great to see that we are having a community like you, steve
and so on. Also thanks a lot for testing all these scenarios. To be frank, even I didn't check
all the scenarios that you mentioned above and it is nice to see all of them are working as
expected. Once again it is the community which drive these open source projects and thanks
for providing us the right guidance.

> I'm using 1.1.1-RC1.  When a connection times out, I can see using lsof pipes being left
open.  This does not happen when the connection works normally.
> Steps to reproduce:
> 1. Check the open files
> 2. Run the SimpleStockQuoteApplication successfully
> 3. Check the open files (open files will go up on the first successful request, but not
subsequent successful request
> 4. Run the SimpleStockQuoteApplication this time with a  -Daddurl that will generate
a timeout.
> 5. Check the open files.  Repeat steps 4 and 5.  The number will continue to grow.
