What happens instead?
NaCl process crashes

Please provide any additional information below. Attach a screenshot if
possible.

This is quite a strange one, a bunch of our users (Videostream) are experiencing our NaCl process crashing on what seems to be a pretty standard interval of five minutes. Our process can even be sitting idle, waiting for commands from our Javascript background page, and it'll crash *every* five minutes. This is happening to users who upgrade to Windows 10 Creators Update and they didn't have any issues prior to this.

We haven't been able to reproduce the issue on our own systems but we were able to have remote desktop sessions with some users to gather this information. Let me know if there is other information I can grab from these users to help figure out the cause of this.

From the Windows System information, I was able to get the following Windows Error Reporting entries:
