Ever have a bug that *only* occurs in your production environment? How do you test potential fixes? 😜

Yeah to often 🙄 though usually I know what will fix it you just can't be sure

If its not a heisenbug, then you can probably reproduce it on local as well. It just requires more effort than the ones you find in a staging environment.

Try to isolate the cause first. Is it data related? Is it config related? What other components are involved that you don't use in your local env?

I never had this because my dev environment is an mirror of the prod environment

Our dev and test environments are a mirror of production and I've still seen errors that only occur in production.

Pain in the tits to fix.

Memory dump and analyze it. Every time a bug has happened in Prod, it was never my fault... I just had to prove it...
