A report ends with "SBOX_FATAL_MEMORY_EXCEEDED"

Hi there,

After migrating reports from 2012 to 2016 (13.0.5865.1), one ends with "Error code: SBOX_FATAL_MEMORY_EXCEEDED" in Edge and Chrome. The error appears after consuming ~7.5GB of RAM. But it works fine in Firefox and it consumes 1.5GB. I'd say it still a lot and probably the report needs to be redesigned, but I'm wondering why the error appears in Edge and Chrome. Also, why it works fine in the 2012 version in all the 3 browsers.

I'd appreciate your help.

Hi @hotbuk-1 ,

"SBOX_FATAL_MEMORY_EXCEEDED"

This is often because of an app or website that uses excessive amounts of memory. I think it may be caused by running the report being too large and taking up more memory. It means that the report used more memory than permitted for the sandboxed process. As for why this phenomenon occurs in Google and Edge, it should be Edge currently sets the same limits as Chrome; the limits are so high (4gb-16gb) that exceeding them is almost always an indication of a memory leak or JavaScript error on the part of the site.
As you mentioned for why this phenomenon in SSRS2016, I think it may be the difference between the versions. There are many differences between the versions of SSRS2016 and SSRS2012. The best way is to re-plan these reports.
In addition,please refer to: SBOX FATAL MEMORY EXCEEDED constantly and chrome is using large amounts of memory.

Hi @Joyzhao-MSFT,

Thank you for your response. I'm going to redesign the report. But still, it wonders me why Firefox can handle it :).

Best regards,

Hi Hotbuk,
My guess is that the memory stack limit set by Firefox is different from that of Google and Edge, and it may also be related to the number of extensions in the browser. I am not an expert in this area, and I may not be able to provide you with an effective reference on this issue.
If you have any issues about SSRS, you can feel free to let me know.
