Hi Kiran - looks like you need to adjust your heap size on your server based on the memory you have available...
Take a look at https://community.talend.com/t5/Design-and-Development/Could-not-reserve-enough-space-for-object-hea...
or http://kindleconsulting.com/blog/entry/managing-jvm-heap-size-in-talend-open-studio.html

Hi,
Is there any cache component consuming two much memory in your job? Such as, tMap, tUniqRow, tSortRow? For a large set of data, try to store the data on disk and allocate more memory to execute the job.
Please have a look at KB article TalendHelpCenter:Exception outOfMemory.

Hello,

With your talend data fabric cloud solution, you does publish the Job to cloud and run it by Remote Engine? or not Remote Engine? Cloud Engine?

For remote engine, you can navigate to the TalendRemoteEngineInstallationPath/etc folder, and increase the value of the parameter in the wrapper.conf file.

Best regards
