When i execute the job i see this error

“Warning: Your system is running low on virtual memory. Total size is <40185>, available space <53>”

Want to know what memory is it.

Can anyone help me out with this.

Thanks,
Kevin

The computers virtual memory (main memory + swap space).

Thanks for the response.

Do i need to improve my Computer memory for it.

And the error is not related to Data Services right?

Thanks,
Kevin

I wouldn’t go that far. The first question is, why does the DataServices process consume so much memory - assuming it is.
Either you cache large amounts of data because you have to for performance reasons or accidentally and without caching it would be even faster.

Hi,

I have similar situation, in which we have more than 80 scheduled jobs and we are getting this error. We are processing Master jobs that runs for more than 3 hours each.
We will not be able to make job level changes now. We are able to find a parameter -
MAX_64BIT_PROCESS_VM_IN_MB=4096
in DSConfig.txt file.

Can we increase the Virtual Memory in this parameter to a high level value let’s say increase 1 GB more?

Let me know your inputs.

Thanks…

The only way without changing the current jobs is to increase the amount of memory available on the machine.

However, if a jobs falls over due to memory usage and you have normally 16 GB available. And you double it to 32 GB, who is to say that 32 GB is enough?

A job consuming too much memory needs to be redesigned.

And with for a example the usage of a data transfer (set to table) there are quick and dirty work-a-rounds available.
