Nik Reiman's questions

I am running an Apache Tomcat 6 website and would like a way to somehow log the amount of bandwidth used for each virtual host on the site. Is there such a plugin or logging class that I could use to achieve this? Or how much one go about writing one?

As a workaround, if I could figure out how to log individual requests along with the amount of bytes transferred (not the size the file, but the number of actual bytes sent on the wire), I guess I could write a script to add them up. I'd prefer some other type of module though, since I'm not so concerned about tracking individual pagehits.

We've just upgraded to Windows 2008 server, and I'm already getting really sick of approving dozens of UAC messages. I normally disable UAC on my personal Vista machines, but I'm reluctant to do this on our server. Is there any particular reason I should leave it on?

I've got a Windows2003 server which I rebooted recently, and now is nagging me about Data Execution Prevention having closed the program "Ms08n.exe". When I press "close message", the dialog just reappears, an error message occurs stating "Project1 encountered a problem and needed to be closed".

A google search for Ms08n.exe turns up nothing, and the file is located in C:\Windows\System32. Is there any chance that this file is malware?

Edit I just downloaded and ran Microsoft's malware removal tool -- it didn't find anything, so I deleted the file manually. I'll try some other malware detection utilities and see if that doesn't find anything more.

We've got a number of web services running through Tomcat which use hibernate/mysql. I suspect that some of them have incorrectly configured connection pools, as after several hours some of the individual apps run out of connections and stop responding. We have been making changes to the connection pool service (in this case, C3P0), but we still need to leave the old versions of the applications on the server for backwards compatibility.

At any rate, I suspect that these applications are also hurting tomcat's overall stability. About once a week, our server stops responding entirely and is unable to serve even static pages. After restarting the service, everything works again for another few days or so. Looking through the logs reveals hardly any uncaught exceptions, so I'm not sure what would be causing tomcat to crash. Nothing remarkable is listed in the error logs before the server quits responding, sadly.

We are also considering switching to JBoss, as it is a bit more "enterprisey", but I'm not convinced it will solve these problems. Is there any compelling reason to switch web platforms, or should I debug further within our own webapps? Also, is it possible for the webapp to crash the application server by doing something bad?

Server config: Windows 2003 Server, Tomcat 6.0.18 + blazeDS 3.0, Hibernate 3.2.
