unless your ram is defective, it's perfectly normal to have a bunch of errors in work units. sometimes even 10-20 at a time.

yeah i just had a bunch of them give errors after running for 50 minutes or so.

i ran memtest86+ for 3 hours afterwards just in case, but there were no ram faults detected

i just let them keep running for hours on end so that the underlying algorithm or mathematics can be adjusted later in the event that it's an actually useful error.

here is a list of everything they supposedly run on here, if you want to look through it:

all the virtualbox instances on my machine require 2.25 to 2.6 gb of ram to run per core

i had to con the manager into running more instances of virtualbox by adjusting ram usage, and in most cases, can't get all 4 cores to run with 8gb of ram.

setting ram usage to 100% seems like a terrible idea most of the time because the virtual machines will over-allocate and cause massive swapfile thrashing that renders the system unusable and the cpu idles at 0% without any work being done. i've had to use 70% ram usage in the memory manager to get 2 cores to process WUs, and 85% for 3 cores. anything higher than about 86% causes 4 tasks to run and then they all just swap to death with no progress being gained.

maybe this prevents more people from using boinc, because any noob to this wouldn't think to do any of that; they would simply think 'sure use 100% of my ram, go ahead', and it results in 0% work being done in certain use-cases.
