@ Profile Wiggo "Democratic Socialist" and several others
Yep, those sticking downloads are getting very annoying here this morning. :-(

I know you are running Linux, but one of the Linux people could convert my Windows CMD file
into a CHRON job to do much the same thing.

This CMD file looks into BOINC to see if anything is in the "Transfer" queue. If there is, it sends a
request to BOINC to retry each of my four projects, then sleeps for a minute before retrying again.
When the Transfer queue is empty, it sleeps for 20 minutes.
Once an hour, it requests BOINC to UPDATE.

I only start this when we are having transfer problems, and stop it when they are cleared up.

=========================================================================================================
@echo off
prompt $T$G
Setlocal EnableDelayedExpansion
SET /A UpdateTime=0

cd /d S:\Program Files\BOINC

:again
set /A WaitTime=1200

for /F "tokens=1,2*" %%I in ('boinccmd.exe --get_file_transfers') do ( if /I "%%I"=="name:" ( set FN=%%J
set /A WaitTime = 60 )
if /I "%%J"=="active:" if /I "%%K"=="no" (
boinccmd.exe --file_transfer http://setiathome.berkeley.edu !FN! retry 2> NUL
boinccmd.exe --file_transfer http://einstein.phys.uwm.edu/ !FN! retry 2> NUL
boinccmd.exe --file_transfer https://lhcathome.cern.ch/lhcathome/ !FN! retry 2> NUL
boinccmd.exe --file_transfer http://boinc.bakerlab.org/rosetta/ !FN! retry 2> NUL
)
)
if %WaitTime% EQU 1200 set /A UpdateTime=%UpdateTime%+1200

if %UpdateTime% GEQ 3600 (boinccmd.exe --project http://setiathome.berkeley.edu update
set /A UpdateTime=0 )

Choice /C YQ /D Y /T %WaitTime% /M "%Date% %Time% Waiting for %WaitTime% seconds. Do it again now? Press Y for Yes, Q quit"

if %ERRORLEVEL%==1 goto :again

Fwiw, I set cc_config.xml <max_file_xfers>5</max_file_xfers>, down from 8, and I'm not seeing further stuck transfers. Could just be a coincidence.

Just tried this. Didn't make any difference. Downloads at max 5 still went to instant backoffs.

not a panic, but an observation.

I've noticed all of my systems experiencing a handful of stuck downloads. it's fixed easily just hitting the "Retry Now" button.
Been occurring for a while, along with the occasional upload taking a second attempt to get through, although it has been occurring more often over the last couple of days.

I see half of each download request go to immediate backoff at the start of the download. I assume this is caused by the added new strain to the servers from the cache limit adjustment.

Any server fine tuning that can ameliorate the issue?

Same here, occurs on my Linux system (no Hosts file setting). No issues on Windows system (Hosts file set to Georgem).
I can't see it having anything to do with the cache limit adjustment unless somehow the larger Work in progress has an impact on Vader- while it does to transition work, I can't see the increase in Work-in-progress affecting that unless it's resulting in data no longer being cached. Likewise for it's Assimilator work.
When it comes to downloads, Vader has always had issues over the years.


Edit- just as I was about to go hunting for my Linux Hosts file & edit it, the downloads started downloading without assistance again.

Yes I just brought the daily driver back online and had to download over a hundred tasks to try and refill the cache depleted by the backed off downloads. They came down with no issues.

Splitters struggling again.
After a large overshoot the Ready-to-send has fallen by over 300k in under 2 hours, and still heading south.

We have between 1-2 hours (262k) in the RTS queue, plus whatever it can split, but it isn't splitting fast enough. There is over 7.2 million out in the field, so hopefully everyone has enough WUs for a bit while the system is slow to split. I can only assume it is busy validating or assimilating or deleting and that is why splitting has slowed down. Hopefully splitting will pick up again when whatever is keeping it busy now is done.

Hi Grant,

I see we're still experiencing server problems, and I've not heard anything about a shortage of CPU tasks, but I have not been able to get any on one of my systems. Getting plenty of GPU tasks , but no CPU tasks. Anyone else having this problem? I did install the new Boinc update but I doubt that that is the problem.

Which host is giving you issues? I see cpu tasks received today on your hosts.

Yes, all others are doing okay for now. The one in question is ID: 8048221. Last server response says that it is out of work, but I have no CPU work.

Your CPU requests were likely in "back off request mode" and that can be for as long as 4 odd days.

There was a simple way to check and rectify that with the ancient BOINC version that I use to use, but I can't seem find out how to do that yet with the much newer version that I'm using now.

Cheers.

I guess I should explain my whole situation, just so there is nothing left to chance. For the last two days I have been given the response from the servers on request for work, that the servers may be down. I had had about 25 tasks to report, but it would not report them. Not knowing what else to do, I did a reset, as much as I hated to and loaded the newest version of Boinc. That got me connected again, but only able to receive GPU tasks.
Well, that's the whole sad story. I was using version 7.6.2, I think.

If you have the Manager running, highlight Seti in the projects tab and then select Properties. That shows you the backoff timeouts for both the cpu and gpu.

You are running anonymous platform. Do you still have cpu applications defined in your app_info?

If running the Manager use the Event Logging flags to set cpu_sched_debug and see if you are even requesting cpu work. For a complete check, set work_fetch_debug and cpu_sched_status flags in the Event Log.
