I don't know if this is the best place to put this but it's not a question so I figure here it should be.
Having spent this morning investigating why my server keeps crashing out after it has been running for a week, I started having a look at the tomcat logs for the days when it hasn't been being used (and to understand why my server usage bill has shot up). I have come to realise that there are some comrades in Russia and China who are overly interested in my Tomcat manager.
Given that I have no actual users at the moment, none of these are friendly, so I have done whois checks and blocked their entire IP range, which I now share for others who want to block update their firewalls.
