java.lang.OutOfMemoryError: Java heap space Java heap space

KarthikGs — Sat, 16 Nov 2024 10:01:54 GMT

Hi,
Today is my worst working day so far.
All the changes i have made to my job in TOS is lost, when i came across this error while saving my job, "java.lang.OutOfMemoryError: Java heap space"
All the changes i have made to my job is gone, and this error still persists. How can i overcome this thing. I have increased the heap memory in this location. And after to saves, this exception again rose to the surface.
" C:\Program Files (x86)\Talend-Studio\studio\configuration\config.ini "
Increased the heap to 1024mb,

-vm
C:\Program Files (x86)\Talend-Studio\jre1.8.0_91\bin\server\jvm.dll
-vmargs
-Xms1024m
-Xmx2048m
-Dfile.encoding=UTF-8

Where shall i increase the heap size to never see this exception again, please specify the name of the file too.

Modify in 'C:\Program Files (x86)\Talend-Studio\studio\Talend-Studio-win-x86_64.ini'
adjust Xms and Xmx for what your machine can handle:
-vm
C:\Program Files (x86)\Talend-Studio\jre1.8.0_91\bin\server\jvm.dll
-vmargs
-Xms5120M
