Memory leak with ssh (org.apache.sshd.server.session.ServerSession objects)

2012-09-14 Thread a_bouchama 
Hello,

We use apache-karaf-2.2.9 in windows 2008 server R2.

I've run a lot of Ssh Echo in a short time. And the karaf memory peaked,
and we receive out of memory as exception.(see the attached picture 
http://karaf.922171.n3.nabble.com/file/n4026025/Jconsole_Karaf.png )

Running jhat shows some classes that should consume such memory:
class org.apache.activemq.command.ProducerId 21706 955064 
class org.apache.felix.gogo.runtime.Token 46536 930720 
class org.apache.felix.gogo.runtime.Closure 9972 717984 
*class org.apache.sshd.server.session.ServerSession 1662 563418 
class org.apache.mina.transport.socket.nio.NioSocketSession 1662 511896 *
class [Lorg.apache.activemq.command.DataStructure; 48 393984 

The memory leak seems to lie around unclosed ssh server session. 

To reproduce the problem, you have just to run this script loopsshecho.bat
that will allow to reproduce rapidly the bug 
http://karaf.922171.n3.nabble.com/file/n4026025/probes.zip probes.zip :

{code}

@echo ON
:again

CALL launch-javaprobe.bat com.eurofins.nagios.probe.ssh.SSHEcho --hostname
Localhost --login karaf --password karaf --sshport 8101
ECHO .
goto again
{code}

You have to change the parametrs of :
--hostname
--login
--password
--sshport

Best regards,
