My Linux box has a problem with the 6.54_x86_64. 4 GB RAM is not enough, other WUs are waiting for memory. The 6.54_x86_64 use all of my RAM and I found only 35 MB free. Never seen this problem with the 6.53. After a update from 6.4.2 to 6.4.5 (I still miss the 6.5.0 for Linux 64 bit) the failure is yet not present, I'm still waiting and have a eye on it. On Vista 64 the application 6.55 is only using 35 MB.
____________

Same things for me on GTX280 and 8800GTS512 graphic cards.
I tried to increase ram settings, it seems to fix the problem.
This problem occurred on Q6600 (4Go ram) and celeron d420 (2Go ram) based computers.

My WU with 6.54 has grown, in approx 1 hour, from 50MB to 180MB and it keeps growing

They released the 6.5.0 for Linux as 32bit, unfortunately there is no 64bit build...

I found the same problem now on one of my systems, BOINC 6.4.2 with acemd 6.54, memory usage is increasing pretty fast:

mC16040-SH2_US-5-40-SH2_US1720000_0

Look at this type of WU, host concerned and the other.
It's a bit frustating.

I've got the same problem :(

this host

Just started a day or so ago.

I have two units on my dualcore, which are mC16040-SH2_US-5-40-SH2_US1720000 and ME12403-SH2_US-4-40-SH2_US950000.

Both are waiting for memory now, the first is stuck at 77%, the second at 35%...

I will cancel the 35% one and hope I'll get a WU of another type. We'll see if that makes the difference.

On my other computer a GPUTEST6 unit is running without any issues...

edit:

can't get a new one :-(
"not available for your your type of computer, bla..."

I have the memory leak too.

My system: Intel-Quad-6600 Opensuse 11.0 bit, Boinc_6.5.0 64 bit, NVidia 260.

In BOINC/slots/0 (this is the slot which acemd_6.54 is using) you will find two files with the same size (output.dcd and output.vel.dcd) and the size of the files is exactly the amount of memory the "acemd_6.54 process" is using).

Both files (and the process) are growing and growing....

I don't have a windows system (with CUDA), so i cannot compare this with the windows-files......
____________

I upgrade to 6.4.5 now, the remaining task stays in "waiting for memory" mode and again I got:

...after a few minutes the files in the slot are growing very slow, but the application is growing with the same speed from the beginning.

(more than 1 Gig)

This morning my Quad was crunching a SH2_USPME-5 workunit (pN16075-SH2_USPME-5-40-SH2_USPME470000) and the memory usage was again increasing. I stopped it and started a GPUTEST6 unit (lY10341-GPUTEST6-1-20-acemd_0), the memory usage is stable, not a single Kbyte more after some minutes... Now I stopped the GPUTEST6 and started one SH2_US (to20339-SH2_US_1-5-40-SH2_US_1240000_0), immediately the memory usage starts growing...

I had already upgraded to 6.4.5 when I posted in this thread about the memory leak.

Btw, I am out of work now, and not getting new WUs. Bah.

Could it be fixed soon please ?

I found now an acemd_6.57_x86_64-pc-linux-gnu__cuda process running, unfortunately memory usage is still growing over the time... CPU usage of that app is ~40% of one core, on a C2D 3,4GHz... Now Windows and Linux change roles? ;-)

I'm running the 6.57 on a GPUTEST6 right now, no problems. Load is at ~8% (normal on my system) and memory is stable.
If I switch back to the SH2_USPME unit I get again increasing memory load and 40% load on one CPU core.

There is either something wrong with the WUs or the apps...
My BOINC Version is 6.5.0.

I'm crunching a WU that uses up to 15% of my CPU and has already eaten over 1GB RAM...

I changed to 6.4.5 this morning and it "leaks" the same as 6.4.2. It take about 4 hours to devours all the memory and takes up all the swap. When it starts to write to the hard drive constantly, I re-run benchmarks and it releases the memory and most of the swap. The wu's are 6.57. It makes no difference if I run another project at the same time. I am running current drivers[177.82] for my card, XFX 9600GSO. Ubuntu 8.04 on a bone stock X2 3800.

Is there something else that I can do or is this a problem beyond my control??

I have a 6.58 WU in queue, so I guess the new version adresses this specific problem. I'll keep you updated about the results.

So far it seems to be working. Good work ;)
