I see on some of my pc's extreme long wu's with estimated runtime of > 2 days.
Faulty data or is it planned?

I just noticed that I've got one WU that's been running for 40 hours (with an estimated 3 hours left).

I terminated one after 43 hours on 25 December. I doubt that it is a proper work unit.

I'm going to abort the long runner I have -- it's made no progress and the time remaining hasn't changed in over 3 hours.

For me, Linux (on this host). It doesn't show in the stderr output, but it had been running for about 43 hours when I aborted it.

That is on Ubuntu 16.10, running on an i7-4790. Nothing is overclocked, at the CPU runs at a reasonable temperature (65 C).

Is there a '10' in the task name near the end? They've been known to take several times as long as normal tasks.

No, it is,

universe_bh2_160803_38_1_20000_1-999999_775000

Sorry, I had not seen the later post, my wu is the one I referred to in my earlier post. Windows 8.1, 4GHx i7 system, no overcvlock. It says it is 4.949% done, some loop after that point perhaps? It seems to have been completed by my wingman in just over two hours.

The one I aborted after about 43 hours was universe_bh2_160803_35_3_20000_1-999999_925000_1.

I released the wu, sometimes stopping and restarting gets things going, but all that happened was the % complete dropped to 4.940%, (checkpoint reload?), but nothing seemed to start, just increasing remaining time, at about 1 minute every 3 seconds. I've suspended it again, thoughts of things to try to help find this problem welcome.

I'm doing some work on another machine and had to power this one off to swap power supplies. The wu started again from 0.0%, ran quickly up to 4.940% then stuck again.

In case it helps with anything that can be identified, here's one I aborted after noticing it had been running for over two days on one of my Win10 hosts:

Weird isn't it? A collection of similar problems from different CPU's running under different operating systems, yet others are completing the same work units without problems in reasonable times. All at this, and only this, project. Interesting.

A 35_1 and a 39_3 never seemed to finish for me. A restart brought down reported elapsed runtimes from about 20 hrs to 25 min and 9 min. I guess the wu:s got stuck at those elapsed times.

all else works fine.

happy new year!

I checked to see if it restarted again, but just the same, no suggestions for anything practical here. Aborted.
