My tor logs (running on Debian) are showing this warning: [WARN] Your system clock just jumped 100 seconds forward; assuming established circuits no longer work.

It may just be that your machine completely hangs for a while occasionally; that will look to tor like a clock jump in that direction. Either hard disk timeouts of some kind, or serious swapping. If VM then also possibly the entire VM being starved occasionally.

This is the case with older versions of Tor (I haven't been active as much recently, sadly) on the Raspberry Pi. When the Pi gets overloaded, Tor thinks there are clock jumps.
