Are you sure this is a bug in Passenger?

Yes.

Question 1: What is the problem? Passenger crashes when upgrading from 3.0.12 to 5.1.x. The application log returns a 200 when a request is made but passenger crashes with a seg fault:

Does setting https://www.phusionpassenger.com/docs/references/config_reference/apache/#passengerdisablesecurityupdatecheck help?

vaseched commented 4 years ago

I'm running into the exact same issue, and setting PassengerDisableSecurityUpdateCheck does not help
