What's weird is that only very rarely (once in your logs) do we seem to visibly crash (as in, we actually get told there's a crash). In most other instances, the application simply quits without a trace, truncating the log file. That leads me to suspect something else might be forcibly causing us to exit. Do you have any kind of anti-virus software installed? Thinking if it might be triggering a false positive. If you do, try disabling it and see if that changes anything.
