NFS@Home

Post by UBT - Mikee »

Been doing this for a few days now without any discernable problems until yesterday.

I decided to turn over all 4 cores to do this project and all was well. Soon after I noticed that the HDD was having kittens! PC was getting very slow to respond. First suspicion was BOINC so I shut that down - no change! Hmmm...

Checked out a few other things and nothing would calm down the drive. Eventually I did a 'System Restore' back to Thursday. That seemed to work then after a few minutes the HDD went off on one again!

'Task Manager > processes' showed 4 instances of 'lasievee_1.07' were using a lot of memory (298,000 Kb each). 'Performance monitor' showed 100% of memory was in use (usually around 50%).

'Ahh' thinks I - 'Windows is getting low on memory and is using the HDD as virtual memory (even though I've got 4 GB of RAM) - how do I sort that and what is lasievee_1.07?'

Yeah - it's obvious now. Abort all the NFS tasks and see what happens. And lo... memory dropped back to 10%, HDD activity reduced to zilch once the 4 instances of Lasivee were gone.

I've now gone back to having no more than 2 instances of NFS running at a time and all is well again!

The thing that threw me was that memory wasn't being released when NFS was suspended and/or BOINC shut down. I assumed that it would have been but I realise now that I've got preferences set to 'leave applications in memory when applications suspended', but I did and it didn't! Image

So the lesson here is...

If you're doing NFS don't have all your cores running this at a time or your HDD may throw a wobbler!

I had a similar problem with this project so I stopped doing it.
I looked through the message boards and found this...

It helped me.
