On Debian 10 Apache2.4 php7.3-fpm Eclipse 2019-3 PDT with xdebug and Firefox xdebug extension installed everything works fine but occasionaly it falls with "Internal Server Error" page.
If I close Eclipse and reload the page, it displays correctly again. If I relaunch Eclipse, even without relaunching Debug and reload the page again I get the "Internal Server Error".
In the logs:
apache2/error.log:
