Hello together,
I am using to Tomcat 5.5.26 Servers. I took over the responsibility for thi=
s system some time ago.
Since then we already got the following error message.
SEVERE: Manager [/mywebapp]: Unable to receive message through TCP channel
java.lang.ClassNotFoundException:
After questioning what this error is about I got no response but the commen=
t that everything is running fine.
So I haven't searhc after it. But now after having a rollout of new servlet=
version we have some serious
performance issues. And now I have to check for every severe error message =
I can find.
But unfornatly I haven't found a solution or cause for this.
The only thing which I have found is a posting that this might be a problem=
of the tomcats version and
that this might be a bug which was solved in 5.5.28. Is this correct?
The cluster configuration part in server.xml looks like a standard configur=
ation:
<Host name=3D"localhost" appBase=3D"webapps"

watchEnabled=3D"false"/>
<ClusterListener
className=3D"org.apache.catalina.cluster.session.ClusterSes=
sionListener"/>
</Cluster>
I found out thatwe are not using the Deployer context. It is just configure=
d, but both Tomcats servers use a
deployment path on its local storage.
Has somebody an idea?
