I have noticed that when I snooze Boinc or setting is "Suspend computing when in use" prst-v3.exe doesn't stop working. Boinc Manager does show that tasks are suspended but process still uses 100% of cpu core. Sometimes it is all processes, sometimes it just like 3 out of 32. I have noticed this behaviour at least two Windows 10 machines and just did notice it in Ubuntu 20.04. If I restart Boinc client this behaviour disapears, but it returns later. Is there problem with application or in my hosts?

Is there problem with application or in my hosts? The app is fine and using the native wrapper from the app itself. What BOINC version are you running? Do you run it on multithread or standard? I will try to test it on ubuntu18 and on win10 Update: no issues if I suspend tasks on win10, BOINC v7.20.2, the tasks do nothing until I unpaused them.

I will try to test it on ubuntu18 and on win10 Every host is running standard. 1st Win 10 host is running 7.14.2, this is "Suspend when active" and have seen this problem many times, all 12 processes are using 100% even when Boinc says suspended. 2nd Win 10 host is running 8.0.2, I just did snooze it and it did have 3 out 32 tasks using 100% Ubuntu host is using 8.0.4 and just did notice when I did snooze there was still 4 tasks using 100% I can't reproduce this problem after I did restart Boinc client. It appears after several hours (tasks, maybe?) has gone by.

Update: no issues if I suspend tasks on win10, BOINC v7.20.2, the tasks do nothing until I unpaused them. Yes, this is intermittent problem, it doesn't always do it but I have seen it happened many times. I will try to reproduce this problem and give more information when it happens.

Cannot reproduce the problem. You can try to debug with <suspend_debug> The taskmanager has 0% cpu load after suspend. That's odd if different of your hosts have this issue.

Okay, debug flag is on, I report if I see this problem again. And yes, it is odd to see same problem with three different computers...

The snooze option is different from what I'm talking. Check your snooze settings in prefs and if you use different computer types like home, school etc, has nothing to do with the app but with a BOINC client setting.

For me on Ubuntu 24.04 with BOINC 8.0.4 I see prst_linux_v3 always run on if suspended or pre-empted by other work. BOINC shows suspended or waiting to run but top shows prst_linux_v3 running. ____________ Paul.

Now problem is back after 12+ hours in Ubuntu and Win 10 hosts. I did suspend and there was still 3 running 100%. Unsuspended and waited 5 minutes then did suspend and there was 4 tasks running 100%. Unsuspend, waited 10 minutes and now there is 9 tasks running 100%.

Same problem with Win 10 host, suspended and firs there was two tasks were still running 100%, then 4, and third time it was 6. Same "[suspend]" event log message in win too, no other information. After restarting boinc clients in both hosts problem disapears. And Paul has same problem so it's not just me.

That is bad. I must check the code. Update Can you also log <task_debug> update2 tests done so far, win7, win10, ubuntu 18, BOINC v7.20/22, Debian 13 with BOINC v8.0.4, all are working so far update3 I thought it could be the BOINC version and installed v8.2.4 on win10, suspend/resume also working as expexted

And You can see that I did command suspend at 18:08:04, but 18:16:08 one task still finished computation. When You are doing test, please let them run many hours before testing suspending/resuming. This doesn't happen when You start Boinc and test suspend/resume. 7 hours ago I did restart Boinc and now I have this problem again.

I took only some of Sierpinski / Riesel Base on 2 different hosts and 4 OS's. I have informed the dev if he can find something in code. I'm out of ideas. Update: If does this happening to other projects then it is a BOINC issue

I have noticed that when I snooze Boinc or setting is "Suspend computing when in use" prst-v3.exe doesn't stop working. Boinc Manager does show that tasks are suspended but process still uses 100% of cpu core.

Sometimes it is all processes, sometimes it just like 3 out of 32.

I have noticed this behaviour at least two Windows 10 machines and just did notice it in Ubuntu 20.04.

If I restart Boinc client this behaviour disapears, but it returns later.

Is there problem with application or in my hosts?

The app is fine and using the native wrapper from the app itself. What BOINC version are you running? Do you run it on multithread or standard?

I will try to test it on ubuntu18 and on win10

Update:
no issues if I suspend tasks on win10, BOINC v7.20.2, the tasks do nothing until I unpaused them.

Every host is running standard.

1st Win 10 host is running 7.14.2, this is "Suspend when active" and have seen this problem many times, all 12 processes are using 100% even when Boinc says suspended.

2nd Win 10 host is running 8.0.2, I just did snooze it and it did have 3 out 32 tasks using 100%

Ubuntu host is using 8.0.4 and just did notice when I did snooze there was still 4 tasks using 100%

I can't reproduce this problem after I did restart Boinc client. It appears after several hours (tasks, maybe?) has gone by.

Yes, this is intermittent problem, it doesn't always do it but I have seen it happened many times.

I will try to reproduce this problem and give more information when it happens.

Cannot reproduce the problem.

You can try to debug with

<suspend_debug>

The taskmanager has 0% cpu load after suspend. That's odd if different of your hosts have this issue.

<suspend_debug>
The taskmanager has 0% cpu load after suspend. That's odd if different of your hosts have this issue.

Okay, debug flag is on, I report if I see this problem again.

And yes, it is odd to see same problem with three different computers...

The snooze option is different from what I'm talking. Check your snooze settings in prefs and if you use different computer types like home, school etc, has nothing to do with the app but with a BOINC client setting.

10k in Sierpinski / Riesel Base - short credit

For me on Ubuntu 24.04 with BOINC 8.0.4 I see prst_linux_v3 always run on if suspended or pre-empted by other work.
BOINC shows suspended or waiting to run but top shows prst_linux_v3 running.

Now problem is back after 12+ hours in Ubuntu and Win 10 hosts.

I did suspend and there was still 3 running 100%. Unsuspended and waited 5 minutes then did suspend and there was 4 tasks running 100%. Unsuspend, waited 10 minutes and now there is 9 tasks running 100%.

Event log debug didn't show much:

23/08/2025 09:27:44 | | Suspending computation - user request 23/08/2025 09:27:44 | | [suspend] net_susp: no; file_xfer_susp: no; reason: unknown reason 23/08/2025 09:27:45 | | [suspend] net_susp: no; file_xfer_susp: no; reason: unknown reason . . . 23/08/2025 09:28:59 | | [suspend] net_susp: no; file_xfer_susp: no; reason: unknown reason 23/08/2025 09:29:00 | | Resuming computation 23/08/2025 09:29:00 | | [suspend] net_susp: no; file_xfer_susp: no; reason: unknown reason

The "[suspend] net_susp: no; file_xfer_susp: no; reason: unknown reason" logs every second?

Same problem with Win 10 host, suspended and firs there was two tasks were still running 100%, then 4, and third time it was 6.

Same "[suspend]" event log message in win too, no other information.

After restarting boinc clients in both hosts problem disapears.

And Paul has same problem so it's not just me.

That is bad. I must check the code.

Update
Can you also log

<task_debug>

update2
tests done so far, win7, win10, ubuntu 18, BOINC v7.20/22, Debian 13 with BOINC v8.0.4, all are working so far

update3
I thought it could be the BOINC version and installed v8.2.4 on win10, suspend/resume also working as expexted

7 out of 32 tasks are were using 100% of core.

And in Boinc Manager every tasks is "Suspended - user request" but progress percentage goes up.

And You can see that I did command suspend at 18:08:04, but 18:16:08 one task still finished computation.

When You are doing test, please let them run many hours before testing suspending/resuming. This doesn't happen when You start Boinc and test suspend/resume. 7 hours ago I did restart Boinc and now I have this problem again.

I took only some of Sierpinski / Riesel Base on 2 different hosts and 4 OS's. I have informed the dev if he can find something in code. I'm out of ideas.

Update:
If does this happening to other projects then it is a BOINC issue
