I had 2 batch 50 WUs server aborted when they were humming along nicely (one had completed 40 jobs and was still going).

I have another one that completed successfully and now is marked "Too late."

These were having no problem running on a quad core with 8 gig of memory.

I've found that some versions of Windows try to keep all of the input and output files of programs in memory while those programs are running. Can't tell if this is related to the problem.

SOME of my computers have enough memory that I wouldn't expect 1 GB per workunit to be a problem, if those workunits are not subject to a 3.5 GB total for all 32-bit programs that one of these computers seems to have. If such workunits need to be run, could you make this a user option, with the default as don't run them?

I suspect that a 64-bit version of the application program might help as well, regardless of whether it will run faster than the 32-bit version.

Same here. I'm running Boinc 6.12.34 (x64) on Windows 7 - 64bits, intel 860 4 cores and 4 logical so total 8 threads and 8Gb of Ram and only Leishmaniasis tasks and this morning my machine hanged up and I had to reboot, almost completely freezed. I could hardly move my cursor and clicks on task bar were not responding. I waited 30min and same story so I have lost many unsaved personal data by a hard reset. :(

At that time I didn't realized it was boinc the problem. Then this evening I was doing some family video editing and I found it strange to get some heavy lags. My machine was surprisingly slow !?! The morning I had to reboot hard, now it is slow, what happens? A virus? I opened the task manager (Ctrl+Alt+Suppr) and noticed that of my 8 threads, 4 were 100% cpu utilized with 1Gb of Ram and the 4 others were sometimes 100%, sometimes 50%, etc... and using 1Gb too.

So in short my 8Gb were almost eaten by Boinc and Leishmaniasis, leaving only a few Mb available for the others programs. Of course lot of swap, I didn't noticed it because I have a SSD so the noise is null and it was also one of the reason my computer was responding slow while editing heavy video.

So now I understand why my machine freezed this morning.

I'm back on another project and everything runs fine as usual.

Good luck to techs to get Leishmaniasis stuff back to normal. :)

As many have noticed, I did cancel the entire Target 50 as well as Target 51. There is a search box that is declared in the workunits that was WAY to large. When this box gets large, then memory usage increase as well. We are in conversations with the researchers and have checked targets 54 and beyond for the search box size, they appear perfectly normal.

I am working on a script right now to grant credit to member who have returned work for Target 50 as target 51 was not released and other targets were not affected. I hope to have things back up and running soon on target 54.

Thanks,

Ok it appears that the grant credit script completed successfully. I have set it up to run during our normal routine system scripts.

I will be starting up target 54 shortly. Again, sorry for the delay and thank you for your patience :)

Thanks,
