We don't close discussion topics unless they are outdated (or some flame war gets out of hand, or it gets so long that new arrivals don't bother reading it and the same points are being made ad infinitum).

I intend to stay alive a bit longer.

Adding the missing time synchronization solved your problem, so far so good. I cannot really explain the background: If the 4 second heartbeat comes after 7 to 18 seconds, it doesn't look like a typical time drift to me, but rather like a conceptual problem like pausing too long, but I don't really know.

Regarding the single new crash, it was a VERR_PAGE_TABLE_NOT_PRESENT error, on a host with plenty of memory. Other users experienced similar sporadic errors in the past, but I don't remember having seen it explained or solved.
