We are seeing a number of 'detected failure on control connection' errors in our logs which eventually makes our system unresponsive.
2012-11-27 19:04:07,242 WARN [org.jboss.remoting.transport.bisocket.BisocketServerInvoker] org.jboss.remoting.transport.bisocket.BisocketServerInvoker$ControlMonitorTimerTask@bbfa5e7: detected failure on control connection Thread[control: Socket[addr=oxford/192.168.30.75,port=4460,localport=52236],5,jboss] (5c4o146e-4limzg-ha0fuq7m-1-ha14020p-q3w: requesting new control connection
The environment we use -
Jboss : 4.2.1-GA
Jboss Messaging : 1.4.5
Jboss Remoting : 2.2.3-SP3
Any suggestions as to what causes this issue? Similar discussions suggest a overload issue on the system, if so will the upgrade to JBoss Remoting version 2.2.4 help?

When people think of the hip hop life, they think of the players - the men who shape the music and the blinged-out lifestyle that comes with success. The fact is the hip hop life is different for the women involved: the spouses, girlfriends or artists trying to define themselves in a world where men are still calling the shots. VH1's new, 8-part docu-soap series "Love & Hip Hop" follows four dynamic women who are connected to the world of hip hop, whether it's through the men they love, or their struggle to be heard as an artist. "Love & Hip Hop" provides a dramatic, funny and sometimes heartbreaking look into the female side of the New York hip hop life as these four women try to claim their own place in it.

[JBoss Remoting] - invoke frequency and classloader

"invoke frequency and classloader"
To view the discussion, visit: https://community.jboss.org/message/775985#775985
--------------------------------------------------------------
Hello world,
I noticed a strange behaviour and i want to knwow if this has already been pointed or fixed.
My client is invoking my remoting server by sending inside an InvocationRequest a parameter that is a complex object.
In fact this object is complex only because it aggragates/composes other object.
On server side, the "invoke" method of my ServerInvocationHandler, shall receive this parameter, cast it in its native (or parent) class and then shall execute it.
(my complex object is not only made to structure passive data, but mainly to be ran).
Most of the the time it works well.
But, sometimes, for some mysterious reasons, it fails an i got the following message :
java.lang.IllegalStateException: BaseClassLoader@38bce164{vfszip:[MYJBOOS_DIR]/deploy/[MY_APP.jar/} classLoader is

Just like if the class wouldn't be in the jar...
May I afford an case?
It may happens if my code to be execuded (brought by my complex object and available in MY_APP.jar on server side) is very short (i.e quick) and if the load of this "invoke" method is important.
It occures rarely if the complex object executes a long task even if it the ServerInvocationHandler is invocated many times (lauching the complex object instances treatments in parallel)
It is systematic if the parallel treatments are fast, on the Nth invocation.
Like if the class disapeared from the jar...
On the beginning, i though it was more a jboss problem that needed a restart.
But after few seconds (if the ServerInvocationHandler is no more requested - time to get cooler ;-)) it may re-work properly.
And then it is able to refind the class in the jar...
Humbly, my hypothesis is it may come from a question of load, of frequency...(size of queue between remoting mecanics and native jboss classcloader?)
Does anyone faced this before?
Will i have a chance to find it out? and to get a workaroud?
For information, i'm still using jboss 5.1.0.GA and i'd like not to upgrade its integrated libs jboss-remoting-2_5_1 and jboss-serialization-1.0.3.GA.
Any advice/hint is welcome,
Thx.
