exceptions in Ignite node when a thin client process ends
Hi,
In my application I am using ODBC + Java thin clients to get data from the
cache(stores in Ignite nodes).
whenever a process using this thin clients is finished, I am getting in the
node logs this exception :
*[07:45:19,559][SEVERE][grid-nio-worker-client-listener-1-#30][ClientListenerProcessor]

is there a soemthing I can do to avoid those exceptions?
Thanks!

Hi, @matanlevy
This exception shows that your database connection wasn't correctly closed.
It probably should be fixed by executing `connection.close()` method before
process using thin clients finished.
Could you please try this and tell the result?

Hi,
This message is absolutely unharmful, however, I agree that server node
shouldn't print this exception since nothing wrong happened there.
I've created a ticket in Jira for fixing this behavior:

Hello,
There is an open ticket https://issues.apache.org/jira/browse/IGNITE-12032 with more details.
In general, It’s ok to ignore this error.
You could try to follow Lev’s recommendations with explicit connection closing.
