Thank you Zhenya. Reducing the JDBC connection did the trick.
But I feel the error is misleading. Error talks about
“java.lang.OutOfMemoryError: Direct buffer memory”. So initially we were
increasing
-XX:MaxDirectMemorySize=<size>[g|G|m|M|k|K]
Thanks again.

Subject: [External]Re: OOME on startup with 2.11.1 and 2.12
The e-mail below is from an external source. Please do not open attachments or
click links from an unknown or suspicious origin.
hello, seems you really use all available memory, of course without heap dump i
have no clue why it`s happen, plz increase -Xmx and check once more.
We are planning to upgrade from 2.9 to 2.11.1. But as soon as we start the
2.11.1 or 2.12 ignite instance crashes with OOME error.
[20:15:05,474][SEVERE][grid-nio-worker-client-listener-2-#34][] Critical system
error detected. Will be handled accordingly to configured handler
[hnd=StopNodeOrHaltFailureHandler [tryStop=false, timeout=0,
super=AbstractFailureHandler [ignoredFailureTypes=UnmodifiableSet
[SYSTEM_WORKER_BLOCKED, SYSTEM_CRITICAL_OPERATION_TIMEOUT]]],
failureCtx=FailureContext [type=CRITICAL_ERROR, err=java.lang.OutOfMemoryError:
Direct buffer memory]]
java.lang.OutOfMemoryError: Direct buffer memory
Some of the pointers
1) 2.9 has no problem.
2) 2.11 and 2.12 crashes even with default supplied config of ignite.sh.
OOM is within a min of startup.
3) No other application is running on the server

5) I have also attached the ignite log.
6) O/S administrator confirmed there are no hardware failure.
If anyone can help how to further diagnosis the issue. We will be grateful.
Thanks,
Sachin.
