A specific product won't load in FE.

[VM 3.8.0.10473, J3.9.27]

Hello,

One product in our store has stopped working in the frontend, the page loads for a long time and eventually times-out with a 504 error.
Both SEF and normal links don't work.
The product works fine in the VM edit page.

The product is published, and used to work fine (but we don't know when it stopped working).

edit: I tried cloning the product. The clone works fine, but the breakdesigns custom fields have not been cloned properly... therefore the clone is not 100% a solution.

How do I troubleshoot this?

Thanks

Custom attributes ?
Other add ons ?
User groups ?
Special prices ?
Calculation rules ?

Anything that links to extra sql queries or complicated HTML constructs could cause this.

How to debug this ? Beats me.  But I have given you some ideas.

Thank you. I've narrowed it down to an excessive amount of custom fields by a 3rd party extension.
Weird that the products used to work until some point in time.
I will take the issue with the developer... thanks again!
