Yes probably. They do not work on "normal" weekends, so why would they work on Christmas?

There should be "enough" workunits. From my calculations there are about 10,000 workunits released in half an hour.

Workunit 235725000 was released at 2022-12-24T22:03:10.
Workunit 235735000 was released at 2022-12-24T22:34:40.
(UTC, of course )

99.9% of them are MCM1-workunits at the moment.

For what it's worth, it appears that at present a new batch of ARP1 isn't built/sent out until the previous batch has completely returned (based on watching the figures in the daily generations stats files.) And that means that the more retries are needed for work not returned in timely fashion (whatever the reason) the longer it will be before a new batch is released :-(

And, of course, OPN1/OPNG are off at present, pending the new target(s), so that leaves us with only MCM1. So be it :-)

And on a different note -- season's greetings to one and all...

Cheers - Al.

P.S. I don't know how long it'll take to get all this batch or of ARP1 back, but the longest delay in the previous batch seemed to be for one or two tasks that took over 21 days from start to finish!

[Edit - noticed a [minor] typo!]

Your machine with 88 threads may be too fast at the moment, I'm afraid, thunder7.
WCG is issuing new MCM-workunits at a pace of nearly 10,000 workunits each half hour.
Earlier I reported:
Workunit 235725000 was released at 2022-12-24T22:03:10.
Workunit 235735000 was released at 2022-12-24T22:34:40.

Maybe 'distributed' is a better term.

I'm also seeing that as soon as a workunit is generated, already some seconds later it is being gobbled up by two clients.

Here are some more statistics, 10,000 workunits (steps) apart from each other:

so we are down to one project.

ARP is intermittent. TB was never at capacity. SCC and OPN are done-ish...

this is scary.
