Job sometimes get stuck (Studio&TAC) on parallize component

Anonymous — Tue, 18 Jun 2019 11:56:52 GMT

Hi,

I have built a Job in Talend DI 6.4.1 that generates temp files, based on context variables. After that, a parallize component should start 4 different oracle inputs. The result is written in the temp files.

My problem now is that sometimes the job runs and sometimes it get stuck (and never come back) after subjob ok ---> parallize. (screenshot)

Any ideas whats wrong here?

thanks for answer 🙂

Lars

Hi,

Could you please provide more memory to the job by changing Xms and Xmx parameters? It might be looking for more memory.

I would also recommend to do Memory Run under run Tab to check the performance of the Talend jobs under various memory parameters.

Hi Nikhil,

thanks for your hint.

Unfortunately there is no difference (with varius memory parameters) . I have no evidence in log for memory problems.

I set the loglevel to debug - no error.

Job just stopped running without exception

I attached the console output.

kind regards

Lars

Hi,

During memory run, it will show the memory usage in graph mode for your reference.

Why don't you reduce the memory parameters to very low value say 256M and then try to read a big file containing millions of records. Right now, your job memory parameters help the Talen job to process the incoming data smoothly. This is the reason why you are not getting any error.
