Hello Nico,

Did you upgraded or migrated from the previous version?

I had face the same issue with the frontend server after migrated from 6.2 to 6.3.

Hello, I suspect it to be an issue with GC settings within the INI File.

  • -XX:+UseG1GC and
  • -XX:+UseConcMarkSweepGC

cannot be used in conjunction, try removing one of those options to your needs and restart the service.

Hope that helps!


Joseph N. thank you - I removed -xx:+useConcMarkSweep and it started and it started.
