Reboot causes tasks to error out?

(moderation:
The last couple days I've had to reboot the computer quite a few times, and noticed that both active tasks had declared themselves complete although only half-finished. Unsurprisingly, they failed to validate. I've been fiddling with some other software (and internet settings), so I don't know for sure that this is related to the reboots, but I could imagine that the program might not always exit cleanly.
Any insight from the logs? Is this a known issue?

Did you shut down BOINC gracefully before rebooting (Advanced menu/Shut down connected client)? Never "kill" the BOINC process from outside!
If not, you might have caught the BOINC client while updating the client_state.xml file and thus rendering the tasks useless yourself.

RE: The last couple days

Too many restarts of a unit will cause a unit to stop processing, as Gundolf said exiting gracefully can help prevent this. This was done to make a unit stop processing if it is a bad unit, you probably got it from your reboots. Don't worry too much about it, the unit will just be sent to some else, you just lost all your crunching time spent on the unit is all. As long as the pc is now doing fine you should more than make up for it with new units.
I would never have thought to

I would never have thought to shut down Boinc before rebooting, I treat it as just something that runs in the background, and would expect it to exit gracefully on its own when the OS tells it the system's shutting down. Does Boinc not do this?
RE: Does Boinc not do

It does, but it needs time to complete the shutdown process. There've been problems when windows introduced "rapid shutdown". I don't know how this is handled by linux.
My question was triggered by the fact that both the tasks you linked to in your first post where cut off in the "Reading input data" phase, which can take a rather long time.
