Monitor and restart Xvfb

[lanceulmer]

I've been using athenapdf for about a month now in a production app and roughly once a week the Xvfb instance dies in the weaver container and we have to restart it. We get a general error message: "PDF conversion failed due to an internal server error". It would really be helpful if the Xvfb process was monitored automatically to keep it alive.

That's interesting. We've been running ours for months at high volume, and we've yet to come across this problem. But considering that there's no supervisor in place, it is definitely a possibility. I'm quite interested to know what may cause it to crash.

Xvfb will no longer be required in v3 as we are going completely headless (https://github.com/arachnys/athenapdf/tree/cdp).
