[resolved] Unhandled event loop exception - Java heap space

Hello all,
I would appreciate any suggestions on managing the memory settings as i have huge tables ( >2million records) that needs to be moved around and i keep getting this error.
Also, any reason why my job is reading a string column as a character from a text/excel input?
Many thanks

Hi,
Have you tried to set JVM as:
-Xms:1024m
-Xmx:2048m? Have you checked document about:TalendHelpCenter:Allocating more memory to Talend Studio?
Best regards
Sabrina

Added more memory to my machine and changed my settings. Works now - thanks.

Hi,
Have you already checked documents about:TalendHelpCenter:Could not reserve enough space for object heap and  TalendHelpCenter:Exception: outOfMemory to allocate more memory  for your job?

Hi Sabrina - I'm still running into issues with this. I've made all changes and i'm running the 64-bit application. It could as well be my machine but i've attached a screen shot and part of the error.
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space. I was also getting a "GC Overhead limit" error at some point.

Many thanks

Hi jitesh.pillai,
There is not enough information for us to diagnose your issue.
What's your OS and JDK version? Have you already checked document about:TalendHelpCenter:Installation requirements?
 Is there any more error log which is located in <Talend Studio installation path>/workspace/.metadata/.log?
Best regards
Sabrina
