I don't know. I think we've provoked Mr. Murphy in every way possible, so by that logic, we can't provoke him any more. :p

Sudden crash indicated by Cricket graphs? Good job they'll be back noses to grindstone soon.

Is it known and anticipated that the AP splitters would be down as of Friday afternoon?

What to believe, what to believe.
Ststus page also shows MB result creation rate is around 21/s. Unlikely if the splitters weren't running. So something somewhere isn't working quite right.

I have been getting more than the usual number of "No work available" messages when trying for work, but after the 5th or 7th attempt it finally gets allocated & downloads. Also notived the Validation & Assimilation queues have been growing steadily, although thy've just peaked & are now starting to decline.

Check the Astropulse graphs.

Sorry, reading AP & thinking MB.

The AP graphs show that the Ready to Send buffer is way overfull. Usually it's about 4,500-4,700. At present it's about 13,000. I expect once the buffer drains to a more normal level (and storage space is freed up again) the AP splitters will kick in again.

The AP splitters have not been running for several hours. I suspect something other than disk space issues.

Yep.
The threshold setting for producing more work. Until the Ready to Send buffer gets below 4,500 i wouldn't expect the splitters to start up again. If it gets below 2,000 & they don't start up, then you can start panicing.

I believe you're partly right, but the AP splitters had been set to stop producing work when the "Ready to send" queue got to about 2500, see the 30 day Scarecrow graphs. Earlier today "Ready to send" reached about 20000 indicating the automatic limiting not working. I think someone had to just shut them down remotely, or maybe there's a last resort safety script which killed them.

When automatic limiting is working the status of the ap_splitter processes doesn't go to "Not running". I think it takes human intervention to start them again, if the queue is below 1200 or so tomorrow perhaps someone will do so.

Copy the link out of the message you quoted, or use the standard page which contains the graph: http://fragment1.berkeley.edu/newcricket/grapher.cgi?target=%2Frouter-interfaces%2Finr-250%2Fgigabitethernet2_3;view=UcastPackets;ranges=d.

Yeah, either unicast packets/sec (above) or octets/sec can be used. There's different preferences for different people. I find octets to be a better measure of bandwidth consumption, seeing how packets can range in their size, but octets (bytes) are always the same.

Is It My imagination or is the server taking a lot of time to refresh and to update?

Someone needs to get out and push, As output and input seem to have almost dropped to nothing.

Possibly. There was a similar dive in the traffic at the same time yesterday. And at the moment the forums are slower than a month of wet Sundays.
