For a few days now I don't get wus on any of my machines (Linux & Windows).
I only receive the message 'No tasks sent', though there are wus available.

No ideas?

My first wild guess is there is no tasks of that type available for your OS - commonly seen on Windows PC asking for PREF tasks,

It would be NICE TO HEAR FROM SOMEONE answering our Questions/Issues that is managing (Project Admin?) the project.

Still no work units. :-(

@Supracore:

As you write, this is a temporary issue. But I don't get any wus for more than a week now and I see a lot of users getting credits.

And still not a single workunit. Please repair the database!!!

SOME COMMUNICATION FROM PROJECT ADMINS WOULD GREATLY APPRECIATED!
Been getting these messages for most of last 12+ hurs now:
6/15/2021 15:50:42 | iThena | Scheduler request completed: got 0 new tasks
6/15/2021 15:50:42 | iThena | Server can't open log file (../log_ithena-boinc/scheduler.log)

---

I am getting the same log file error.

For a while now, all my hosts were receiving no work. No errors, just "No tasks sent" message in the logs.
Resetting the project on each host cured this problem for me.

---

This problem seems to have reared its ugly head again. Server status shows LOTS of available WUs, but none of my machines (10, if you include VMs) are getting any work (mix of Windows and Linux).

Hmm. My hosts are receiving work at the moment. Have you tried a project reset on one of your hosts?

We are back to the NOT GETTING WORK AGAN on Windows PC's / PREF tasks!
Looks like the SERVER STATUS PAGE IS ALMOST 1 hour behind:

SOMETHING IS WRONG WITH THE SCHEDULER/PROJECT TASK REQUEST!

On one of my PC's (host 5043) I constantly kept getting the following message >

iThena Not requesting tasks: don't need (job cache full)

even thought it had NOT SENT OR RECEIVED ANY TASKS IN ALMOST 9 HOURS:

153362894	154983024	17 Sep 2021, 13:31:49 UTC	17 Sep 2021, 13:37:01 UTC	Completed and validated	139.18	0.22	2.00000000	iThena PERF v1.03

windows_intelx86

To resolve the problem I had to do a PROJECT RESET and it still took almost 30 minutes to receive new tasks.

I have seen same thing on all of my other PC trying to get tasks from this project over the last month or so and only way to start receiving tasks again is to a project reset or detach/reattach.

As you can see the projects scheduler is very erratic in sending new tasks out:

THREE THINGS NEED TO BE ADDRESSED BY THE PROJECT ADMINISTRATORS:

1) NO TASKS (WINDOWS PREF) BEING SENT ACROSS ALL MY HOSTS

9/29/2021 01:20:56 | iThena | Reporting 1 completed tasks

9/29/2021 01:30:03 | iThena | Project requested delay of 303 seconds

2) CAN WE GET A FIX FOR THE Not sending work - last request too recent AND Project requested delay of 303 seconds WHEN WE HAVE NO TASKS ON OUR PC'S?
--- A FIX CAN QUIT WASTING YOUR SEVER BANDWIDTH & REDUCE OVERALL SEVER LOAD.
--- 303 seconds (5 Minutes 3 Seconds) "delay" is EXCESSIVE when tasks take a bit over 2 minutes each. Maybe reduce it to 153 SECONDS (2 Min 33 Sec) delay?

3) A PERMANET FIX FOR THE SERVER DISK FULL "ERROR".
--- Keeps happening every few days now. A well-run and well managed project should RARELY SHOW THIS MESSAGE TO USERS.

I have the same on just one Windows box. Other Windows machines have no problems, none of my Linux systems (both x64 and ARM) have either.
