Sorry, I haven't been paying a lot of attention.

The first thing I notice is that you have all of your code in the OnStart event handler. This won't work as the SCM is expecting a quick response. The best way is to create a thread to handle the work and return immediately.

I had to completely re-write the service I use. I no longer use Service Broker (probably due to a lack of experience, I had some issues). I also had to create a separate thread for each process being logged. I then had memory issues, so I used a series of queues and queue managers, which solved the problem.

If you would like to get a zip of what I ended up doing, please, let me know.
