On one host I just had 16 work units restart from Zero after they had been running from 11 to 17 hours.

They are all back up to about 0,5% after another hour or so

The percentage done is what has been reset, the run time is still ongoing as normal and some work units have passed 18 hours now but I am not at 1% done.

Why did they all restart at the same time, the computer was not stopped or restarted, BOINC was not stopped either

These are likely jobs running an old, buggy version. The CPU implementation has been made more lightweight in the new version; cancel any tasks that haven't started and any that are stuck or hung.

The Android application is extremely lightweight, yet it still feels heavy; it looks like there will be a need to disable the Android app for BTC Puzzle and Certicom. Regarding *Kampylos: Gravitational Microlensing Progress*, we can assign the task to Android devices that will run it more accurately and quickly.

I don not care about long runtimes.
But reseting to 0% is a general error and can happen on any moment in time a WU is running if a system has to reboot.

Just dumped another lot of Potamos work units on the same host. After more that 12 hours they all went back to zero.

Losing a lot of hours but hope that it helps you find the problem, that's what our testing does, finds and solves faults.

You'll see I will get some points soon, it's been 2 days so far, still early.
