You could add to this list:

I just aborted it, since console F2 said:

There's 1 success in MC Plots database for that description.

Thanks, the list was based on 'only' 8 attempts for each description, but it seems more attempts could result in a success and your's was a fast one: 3 hours and 22 minutes.
One may build an own list from http://mcplots-dev.cern.ch/production.php?view=runs&rev=2363&display=all and filtering on keyword sherpa.

Edit: reduced the previous sherpa list from 613 to 577 occasions.

hello Crystal Pellet,

There is a "boinc ee zhad 206 - - sherpa 2.2.8 default" on one of my machines, NOT contained (yet) in your list - 22 hrs 35 min elapsed, 1108 days left (number is increasing); I guess I can abort this task, right?

P.S. I just found it in http://mcplots-dev.cern.ch/production.php?view=runs&rev=2363&display=all
with 54000 / 18 / 3 / 5 / 10

but still, the increasing number of "days left" is indicating a failure, isn't it?

When it's not in 'my' list, it will never come on it.

3 successes. It's up to you to gamble between a great disappointment and great satisfaction ;)

Increasing left time means not always that a task will end in an error, but that it's surely a heavy task.

I, myself have seen successes after such an increasing left time suddenly jumping to event processing.

Out of interest, what does the "2363" refer to?

For "PbPb heavyion-mb 2760" I get
run events attempts success failure lost
PbPb heavyion-mb 2760 - - pythia8 8.235 default 0 10 0 6 4
but 265306266 is still running and reporting "events processed" to the log (I'm estimating an 80-hour run time).
Or is lost a badly-chosen euphemism for still running?

That is the revision of MC Production -> http://mcplots-dev.cern.ch/production.php?view=control

PbPb heavyion-mb 2760 - - pythia8 8.235 default 0 10 0 6 4

No, probably not. In theory you could be right, but a task would be running then for weeks and weeks, I think.
I don't know when a job is declared lost (No return, but since when?)
The last number of your job description (after the # events) is the attempt sequence. It will be something like 40 atm.
In the list it's still 10.

The answer is that it is, of course, 42! See other thread.

meanwhile, "left time" has jumped up to 4983 days. Should I get worried by now?

No - as long as there are no Vogon ships around.
Just prepare a towel.

I think that's my point - it looks like lost (which has negative connotations) is being used for everything which hasn't yet returned a success or failure, which could be for entirely reasonable reasons such as still being queued or running.

Try to grep the log file for events or elapsed - this can make it easier to see if there's any actual progress.

But a continuing stream of ISR_Handler errors is usually a bad sign in my experience.
