@Nonexistent_Admin

What are causing these errors:

10:26:44.089527 ERROR [COM]: aRC=VBOX_E_INVALID_OBJECT_STATE (0x80bb0007) aIID={b2547866-a0a1-4391-8b86-6952d82efaa0} aComponent={MachineWrap} aText={The given session is busy}, preserve=false aResultDetail=0

Also, noticed the Windows 8.1 machine with the invalids RAID 0 BOINC partition was underperforming by 35%.
Reformated to 32kb blocks from 4kb blocks but still 100% invalid results.

Hello

More than 450 tasks processed on my (old) iMac and only 8 tasks in error : cool.

All these errors between yesterday and today, though.

Check this one. (log is too long for me to post it here)

I confirm the memory requirement is quite high on the mac too (up to 2 GB per task), even with a 16 GB RAM machine I had to limit to 4 tasks at a time to keep a usable machine.

If you pause the WU's then open Virtual Box Manager and look at the settings on the boinc2docker; it has the VM's set to use 3072MB of RAM, although once running on the host, they never seem to require more than 1.7GB of committed (RAM+swap) on Windows 7 but haven't inspected every task and they could potentially peak at 3GB usage.

I would love to use all the memory I have. The main problem for me (I can live with the errors for now) is that the work units are too short. They run for less than 5 minutes, and usually less than 3 minutes, especially on my new i7-9700. That fills up my BoincTasks log, and also creates a lot of network traffic. How about 1 hour work units, though 2 would be better?

The nanohub tasks do not seem to have a peaceful coexistence with other projects running at the same time (I always do this), especially if you have to reduce the number of tasks due to resources consumption. I was forced to reduce to 3 at the same time, and i had odd behavior of tasks "not running for a long time" (and not using any CPU), or kinda blocking the other projects tasks to run...

Also it downloaded a huge number of tasks (several hundreds) when I have a reduced cache setting (one or two days max), the deadline was getting close and I had to cancel a whole bunch (I didn't wait for boinc to do this eventually).

At the moment it is not requesting nH again anymore because it is happy crunching other projects, but I assume it will again .

Hi.
I'm running an i5 with only vbox projects on two of its cores: Cosmology, LHC and NanoHUB.
While the others occupy both cores per work-unit, NanoHUB only uses one, thus running two work-units at a time.
Rotation with the other projects is just fine.

Don't observe the behavior on my other machines though.

When can we expect new WUs?
