That just mean the client socket disconnected, which is self-evident if
the web server crashes.

The second is not the log message, you omitted the message. It's probably
just noting the filter restarting when the pool restarts.

Not reproduce, no. If there were a reproducible issue, I'd have fixed it.
It's very hard on Windows to get a stack trace from the crashes, and
without the debugging symbols there's not much information in them anyway.
If the issue is reproducible, then I can just debug it locally. Without
that, I don't have the time to even think about looking at it.
