Investigating Frog FM generating 0 size images

Found our image genartion is creating 0 size pngs. We investigated 3 avenues Frog.FM with Bun, Frog.FM with NodeJS, Frog.FM with NextJS. The results were escatitc.

Our test case was to generate 10k images with 'wget {url}' which will return a PNG. The script was simple enough

 ```for i in {1..100}; do wget -q http://localhost:5173/test; done```

In summary all 3 avenues failed genearting images of zero size. So we are in the flux to find the best way to create these images. However the error was different for all 3 results.
I had my bet on NextJS but that also failed. Does anyone kept it working under large load ?

Last hope
 For Forg.FM Bun and Frog.FM NextJS the failure is not resulting in stopping of process. However for NodeJS the process exists, this is a great value because we can restart the process which inturn will fix the issue.
 We are going to add auto-restart with process and it's going to help serve the community better.

While load testing Bun we found it's failing to allocate memory in ReSVG and failed with below error.
