As I wrote, I just call a helper function, which in theory should never be needed to be called. So rsyslog is already doing more than what it is supposed to do. Plus, this example is totally theoretical. We use that function call since around 8 years, and never had a problem (remember that your case is an actual memory leak!). We very very very occasionally had problems in the years before we called the helper.
