Re: Unhandled event loop exception (Java Heap space)

Hi,
We cannot repro your issue on our side. What's your OS and JDK version? On which build version you got this issue? Have you ever executed your job successfully in your current studio?
More information will be helpful for us to diagnose your problem.

Re: Unhandled event loop exception (Java Heap space)

Hi,
We don't get this error before. Did you make some change on your existing projects?
 We saw you put your topic under "Data Integration on Subscription..." category. Are you using Talend Subscription Product 5.5?
If so, could you please report a ticket on Talend Support Portal so that we can give you a remote assistance on your issue through support cycle with priority?

Re: Unhandled event loop exception (Java Heap space)

Hi,
We have moved your topic from "Data Integration on Subscription..." to "Open Data Integration..".
Did you make some change on your existing projects or did you config some setting on your window server to achieve "Remote" on talend open source?

Re: Unhandled event loop exception (Java Heap space)

Hi,
You need backup the workspace and all projects, and then delete the workspace and restart the studio, import the existing projects into the new studio.
Here are documents about:TalendHelpCenter:How to export a project and TalendHelpCenter:How to import projects

Re: Unhandled event loop exception (Java Heap space)

Hi,
Sorry for delay!
With open source, we won't be equipped to give you a remote assistance. 
It's a little hard for us to repro your issue on our side. Does this issue still repro on other build version? 6.1, 6.2? Have you tried it on other servers(win7, Linux...)?

Re: Unhandled event loop exception (Java Heap space)

Hi,
We are running the same version in another server without any issues. I am not sure whether we can try it on a new Talend version since we are migrating data from lotus to Oracle. Kindly help in some other way possible.

Hi,
Can anyone help here?
I am tired of asking for help here. Giving a solution and staying quiet for couple of days is not acceptable.
Please provide a resolution to this issue.

We cannot repro your issue on our end. Could you please create a jira issue on Talend Bug Tracker?

Re: Unhandled event loop exception (Java Heap space)

Hi Sabrina,
I have got a new issue now. My ETL job gets stuck in between. We are copying data from Lotus to Oracle DB. Also fyi, we are copying 55 columns data from Lotus to Oracle.
When i ping the Lotus DB server i can see a packet loss of 4%. Could this be the reason for the job getting stuck ?
If yes, then how can i make the job to continue running again. What is the impact of this ?

Re: Unhandled event loop exception (Java Heap space)

Hi,
We see that there is a warning   on component toracleinput. What's this warning?
Can you successfully connect your oracle DB by using  DB connection parameter directly without context?

Re: Unhandled event loop exception (Java Heap space)

Hi,
From the screenshot  you provided, we can not see the whole wok flow.
Did you use  tOracleConnection in your job work flow?
If so, have you already dropped  a tOracleConnection into the job for the tOracleInput component(OnsubjobOK )?
Best regards
