100 % CPU utilization while opening Talend

[Banupriya]

when I open any job in a designer. In fact this seems like some memory leak because when I turned on showing heap status (Preferences->General-> Show heap status) I see that when I have any job opened in designer (just opened not run) memory is quickly running up to some level and then is freed (garbage collector) and that happens all time in cycle  and that is when cpu usage goes up to 100%..When I close designer heap status and cpu goes back to normal.

Configuration: 16GB RAM 64 bit

Version Talend 7.3.1

Hello,

Have you tried specifying the amount of memory for the job to use - in the job's Job tab? This will dictate how much your JVM requests when it's instantiated?

When you execute single job, what is the CPU utilization? Which job is taking highest CPU utilization?

What are the file sizes?

What complex transformations you have ?

What is the processor?

What other processes are running and their CPU utilization when job executes?

Can you pl get some information on this, we might get some clue from above checks?

Best regards

Sabrina

Hi,

The issue not while running the job. I am not able to open the jobs or export the jobs as well. When I open the Talend itself the CPU Utilization goes to 100%. I am getting Heap size issue as well.

What are the file sizes?: We max data as 2000.

Have you tried specifying the amount of memory for the job to use: I have set XMS- 1024 XMX -4096 in

What complex transformations you have ? Total 70 jobs. In 2 jobs each job have 4 t maps and each joining one main and 2 lookups. In 68 jobs each job have 4 tmaps just to loading data from source to target with simple transformation on columns.

What is the processor? Intel(R) Xeon(R) CPU E5-2667 v2 @ 3.30GHz, 3300 Mhz, 1 Core(s), 2 Logical Processor(s)

What other processes are running and their CPU utilization when job executes? only Talend is running

Thank you for your reply.

Thanks,

Banupriya.
