I brought this up in the PS3Grid Forum but apparently as usual nobody took me seriously. Whats happening is the BOINC Manager in Win 64 is slowly taking up all of your memory until the PC won't run or acts very sluggish & will start to Error out the PS3 Wu's until you Re-Boot & that refreshes the memory again.
A simple solution for me on the Win 64 Box's is to not leave the BOINC Manager Window on any Manager Window that has activity. By activity I mean like Time Counting Down until a Project Updates it's self again. I noticed by watching the Task Manager & BOINC Manager @ the same time that for every Tick of a Second in the Manager the Managers Memory usage increased. I've seen it's usage get as high as 5 Million MB. So now I always before Minimizing the Manager put the Manager Window to either Statistics or Disk, this keeps the Manager on Win 64 Box's from slowly sucking up all the Systems Memory Resources & I haven't had a PS3 Wu Error out since I've been doing that.
Try it & see if it works for you Bender or anybody else too, this works on the v6.3.14 that I'm using but would probably work on other Versions too, hopefully or maybe the next Version Release won't need this simple work around ...![]()
