Hi!
Actually there was no OOME before VisualVM connect attempt. There is a
point in time after Ignite start after that it is not possible to conect
VisualVM to Ignite.
I can connect them successfully on different computer.
I think this is an environment specific bug, somehow related to
windows+hyper-v+amd cpu

Hello!
I don't think you can connect VisualVM to JVM in OutOfMemory state.
You can try to use jmap to take heap dump, failing that, try to
increase heap size and/or connect before it goes into OOM.

Hi!
I was suggested to use VisualVM as a debugging tool but can't
connect it
to ignite process.
I start bin/ignite.bat script and point visualvm to ignite process.
After that I get default os window "java platform se binary has
stopped
working"
Cmd console contains
[00:40:19,549][SEVERE][tcp-disco-ip-finder-cleaner-#8][TcpDiscoverySpi]

Press any key to continue . . .
I connect VisualVM to other apps with success.
Thanks.
