Chris,
It is fatal and keeps throwing the error. I have to restart tomcat as the
apis stop responding.APIs return 502.

Sure I will use DNS and try to change the service calls.
Also once in a while we see the below error and tomcat stops serving
requests. Could you please let me know the cause of this issue ?

Mark,
There's no particular reason why a request to node1:/app1 needs
to have its loopback request call node1:/app2, is there? Can
node1:/app1 call node2:/app2?
Yes we can do that but then we would have to use the DNS urls and wont
this cause network latency compared to a localhost call ?

As you described I have added two new connectors in server.xml and using
nginx to redirect requests to different connector ports. Also configured
nginx to route traffic of each app on a different connector port of tomcat
In config of each app I am using port specific for the app which is

You'd have to use multiple elements, which means separate
everything and not just the . It's more work on the Tomcat
side with
Chris,
On single tomcat instance how to map each app to different port number?

Chris,
You might want (2) and (3) to have their own, independent connector
and thread pool, just to be safe. You don't want a connection in (1)
to stall because a loopback connection can't be made to (2)/(3).
Meanwhile, it's sitting there making no progress but also consuming a
connection+thread.

So you encrypt between the ALB and your app server nodes? That's fine,
though nginx probably won't
Chris,
Nginx is being used for image caching and converting https to http requests
before hitting tomcat.
The behavior I am noticing is application first throws Borken pipe client
abort exception at random apis calls followed by socket timeout and then
database connection leak errors. This

Your CPU and RAM really have nothing to do with it. It's more about
your usage profile.
For example, if you are serving
Chris,
Thank you for the input. We will upgrade tomcat and also text on the linux
vm. I read the documentation of tomcat that maxConnections parameter
refers to the number of connections it can serve. If we have 18 core CPU

Both NIO and NIO2 are non-blocking.
previously I was using HTTP/1.1 connector, recently I changed to NIO2 to
see the performance. I read that NIO2 is non blocking so trying to check
how this works.
which connector protocol do you recommend and best configuration for
the connector ? Which stable version of tomcat would you
