Ioannis Canellos commented on SMXCOMP-758:
------------------------------------------

Jean-Baptiste Onofr=C3=A9, indeed servicemix-http 2009.01 uses Jetty 6.1.14=
 whereas servicemix-http 2010.01 uses Jetty 6.1.22.

In one of the projects I have been working on I used 2009.01 built using Je=
tty 6.1.22 (to avoid some bugs that were resolved after 6.1.15). I experien=
ced a similar behavior.

I exposed Jetty's connection pool via jmx  and I saw that there in some occ=
asions*, a lot of connections were marked as idle (and eventually run out o=
f connections, the max connection number was reached and all connections we=
re marked as idle, but none of the idle connections was used).

This issue is solved for me if build servicemix-http 2009.01 using jetty 6.=
1.15.

*: By some occasions I mean keeping a steady low traffic and periodically s=
witching to no traffic.

Also note that since version 2008.01 of servicemix-http the only version of=
 jetty I found to be production ready was 6.1.15 (I've tried combining serv=
icemix-http with various jetty versions).

> I upgraded from servicemix-http-2009.01 to servicemix-http-2010.01. While=
 running some stress testing  (about 7 messages/s)  after about 7000 exchan=
ges  none of my exchanges for http provider go through. I debugged and foun=
d that in HttpDestination I had a maxConnetions of 32 connections and 32 co=
nnection objects in _connections. No new connections are made. There is no =
way to recover from this problem and I have to restart service mix to relea=
se the connections.=20
> If I revert back to 2009.01 all is working perfectly.
