Java Heap Memory Error

Ray0801 — Wed, 10 Feb 2021 03:16:08 GMT

Hi,

I am running a full load job from mysql to mysql there are only two components the target and the source DB components.

On running it,I am getting Out of memory Error.

I read the other articles regarding this issue,it was suggested to increase the memory size,I have increased it to 8096 and I am still getting the out of memory error.

This job was running fine,before for about a year and has suddenly been throwing this error for the past 2 weeks.

WE are using Talend Open Studio Data Integration 7.0.1

I have attached the error screenshot.

Did you upgrade the Java version or database version recently?
