If you suspend the client through BOINC Manager or Mindmodeling WU get's suspended because of a 30 or 60 minute work swap, they remain in RAM taking up resources that another project needs even though the setting to allow work to remain in RAM is specifically unchecked in the BOINC manager.

Verified on 3 machines.

Hey marmot,

Suspending the task and it taking up ram is normal.

There is a setting for your account under memory called "Leave non-GPU tasks in memory while suspended" make sure you don't have that checked on.

Thanks for supporting us and happy crunching,

Brandon

That box is not checked.

I was careful and verified that before posting this bug report.

I'll take a look at this and let you know if I find anything.

Have you seen the same thing?

I have verified this on another 2 machines now, Windows Vista, 7, 8 and 10. The WU will not leave RAM when BOINC is overall suspended nor if MindModeling is specifically suspended. There can be up to an unclaimed 900MB of working RAM locked unless you use a process manager to reclaim it. Of course using process manager to kill the WU ends in a computation error and lost time.

This is bad behavior for an application that is sharing workspace with other projects or user applications for non-BOINC purposes.

I can confirm that this does happen to me also, and some of the processes tend to stick around even after I exit BOINC, only terminating and clearing from RAM after a few minutes.

We are currently looking into this issue.

I will keep you guys updated.

Thanks for supporting us and happy crunching,

Brandon
