Java Runtime Environment Native memory allocation (mmap) failed to map bytes for committing reserved memory

MattE — Sat, 16 Nov 2024 02:45:46 GMT

Hi,

I've got a job which runs fine on my local machine, but when i try and run in the cloud i get the error message below. It looks like it's trying to allocate more memory that is available on the EC2 box (16Gb). How do i set the jvm settings for a job published to TMC?

I have tried unticking use specific jvm arguments in each job.

Thanks

Thanks but i don't think that is quite the answer.

To be clear we have dozens of other jobs deployed and running everyday in TMC but just this job seems to error and I'm not sure what i've done differently or how to fix it.

This was fixed by lowering the VM arguments to

-Xms1024M

-Xmx4096M

In both

Preferences>Talend>Run/Debug

and also in the job in the advanced setting in the run tab
