I am running H2 1.3.176 as a server and H2 1.3.174 as a client. Recently I was having trouble with database responsiveness. After restarting both the server and client, using the "Test Connection" button in the client led to a long pause and then this stack trace.

I am using this code to run the server as a daemon. Any ideas? Googling didn't find me any references to this as a known bug.

from that i found my connection to database is OK
i try that from other servers in my company and Weblogic 12c with JDK 8 and get "Connection Reset" error again
i try in my local Weblogic on Windows OS and get success
So... What can i dooo
Can you please check a few things like :
is the connection successful from console when you try to test the
datasource?
is there any firewall restricting the connection between your DB and Weblogic server.
what is the driver that you are using for your production and is it
the same as of your windows PC?
is this happening everytime or is it an intermittent issue?
check the below thread for some more hints :

The NullPointer is at the place where 'item' is read and this happens intermittently.
Any leads!
TIA!

I don't even have a clue where to start troubleshooting this. ANY help would be awesome!
It seems your connection url, username and password values are not proper.If these three things are proper then the connection will be created.Check in your Jasper server configuration.

I don't know whether you have solved the problem. I met with the same problem as yours (Same configuration as yours too) and trrie to solve it.
Problem location:
public List call() throws Exception { ... List
tokens = getSubSplits(keyspace, cfName, range, conf); ...
In the method getSubSplits when calling method
createConnection(host, ConfigHelper.getRpcPort(conf), true)
, the format of host is not right. It is hostname/10.197.34.111 sometimes (ip_address), so createConnection will fail. We need to extract the ip address and then call createConnection.
You can try to change the code and try Hadoop again.
Good luck!
I'd be very pleased getting help from yours so many thanks in advance.

Thank you a lot again.

Good morning.
Well,we've discovered the solution,kinda easy indeed.
The propertie -Djava.rmi.server.hostname=hostname was pointing to localhost instead of ip.
I Hope this info be usefull to someone more.
Thank you very much.
Regards.
