I don't remember the details now, but at some point TWS started sending an additional (unrequested) message upon connection, I think ManagedAccounts. I had to update my library to parse this message since I hadn't needed it previously. This was before the 'V100' protocol so there were no length headers that allowed a client to skip over messages it wasn't interested in.
One of the sneakier aspects of using the TWS APi is that you can't assume anything about the order of messages. Hopefully it won't be too much of an effort to get back going.

The logs gave me enough information to identify a deadlock in my code.? The event sequence must have changed slightly revealing the bug.? Now all have to do is figure out a fix.
