Asankha C. Perera commented on SYNAPSE-225:
-------------------------------------------
Jef / Steve
Thank you both for bringing this to our notice and helping us to fix this..
although we did test and continue to use the free JProfiler license we have
been granted - whenever we get the time, to make sure we release resources etc.
some times I have seen leaks which are much more difficult to notice or figure
out. These are best figured out by observation, analysis and human intelligence
and code review.. and we are truly lucky to have great users like you to help
us with these!
cheers

> 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.
