Affects Versions: servicemix-http-2010.01, servicemix-http-2009.02,

Hi all! i have been facing a connection leak when using new http provider
endpoints.
The component consumes linux kernel's file descriptors when provider endpoint
points to non existing URL.
To test it, i have attached a single http proxy that consumes requests that are
sent thro a http provider with a wrong target URL. it can be consumed using the
following line:
wget **serviceURL** --post-data="<msg>amsg</msg>"
Each time a request is done, a file descriptor is consumed but released. It can
be detected by counting consumed file descriptor:
ps aux |grep java # helps to determine which SMX process id
lsof -p **smxProcessId** | wc -l #counts smx file descriptors
As long requests are done, last command line will show an increasing usage fd
count. Then maximum allowed file descriptor is reached, SMX stop working
because it cant open any kind of connection.
Regards
