Avoiding IPv6 with extra JAVA_OPTION #347

Closed bbaassssiiee closed 11 months ago

bbaassssiiee commented 1 year ago

Some distributions have two entries for localhost in /etc/hosts:

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

This can cause Java apps trying binding using IPv6, which fails when that's disabled. This causes some tcp ports not listening, like the Artifactory router service.

Solution: add an extra JAVA_OPTION: -Djava.net.preferIPv4Stack=true.

@bbaassssiiee Thanks for raising this issue. Did you had a chance to test this change from your end ? if it is tested then please provide us the artifactory-service.log with enabling this artifactory_extra_java_opts: '-server -Xms512m -Xmx4g -Xss256k -XX:+UseG1GC -Djava.net.preferIPv4Stack=true'

@bbaassssiiee we would like to include in this readme instead of default in vars.
