  • Closed as program error.

Error description

  • When public pages expire, they get reloaded. During this reload
    an invalidation of AccessControl Entitlement caches takes
    place.
    This invalidation lead to hanging threads in the WAS DRS.
    The invalidation is only necessary for certain use cases.
    
    The fix introduces a new config switch with default value false.
    
    It can be changed in ConfigService.properties by adding a
    property with the name
    content.public.page.reload.invalidate.anon.user.entitlements and
    the value true
