Ignite communicating with non ignite servers

[ignite_user2016]

Recently, we migrated ignite to JDK11, all works well except when we run our
security scan, ignite node tries to connect on that servers and result in
out of memory and heap dump errors.

Is it possible where we can stop that scan server connecting to ignite ?

Any configuration ?

help is much appreciated.

And I have observed that ignite visor is also broken where it cant give us
the states for nodes, memory and CPU.

Thanks..
Rishi

Hi,

What security scan tool do you use?

we use Nessus security tool, and the module is Tenable.sc which scans the
vulnerability on spring boot app which runs with ignite client.

Hello!

Well, you could enable SSL on all ports, in this case you can block off the security scanner.

We never had this issue on JDK8 and it run with lower memory 2g but now switch to JDK11 and 4g memory is not sufficent.

We have SSL enabled on all servers but some how it s trying to attempt
connection on SSL causing heap dumps. Is there a way to disable to external
server try connecting to ignite ?

Hello!

I don't think it should cause heap dumps. Here you are showing just a warning. This warning may be ignored.

It's outside of scope of Apache Ignite to disable something else to try connecting to it. If you have invasive security port scanning, you will expect to see warnings/errors in the logs of any network application.
