It looks like the problem is on php side.

hi,

i’ve seen similar issues with apc enabled on php side. on my
installation nginx returned an error 5xx as well when upgrading typo3
core. may be restarting your php (or at least clearing byte-code-cache)
helps.

regards,
chris

You should check the error log of your application server (php-fpm,
apache, or
whatever you use).
