Apache crashing – hhtpd.exe and StackHash

I installed WordPress on a Windows 2012R2 server using xampp with the latest versions of apache and php. I am having intermittent crashes, and they are becoming more frequent. I’ve searched the Apache and Windows forums, and I see it’s a common problem, but nothing I’ve tried fixes it. This is the error message I get when Apache stops:

Has anyone seen this? Were you able to fit it?

Thank you.
