This error is irritating. Especially as there seems to be no attempt to fix it.

I'm not going to waste my time and money on it.

Bye.
2) Message boards : Number crunching : Work unit errors (Message 951)

Running Windows 10.

I have now had the same problem. A work unit failed immediately up being restarted at 00:00:00. Obviously it is a rare occurance but still a waste of time.
Looking at the stderr output I noticed one thing.

I assume that "c:\temp\" is the real name of the folder and not some indirect reference to somewhere else. If it is an indirect reference then my following statements are not relevant..

I do not have a folder named "c:\temp\". My temp folders are on another disk. If you are going to use the system temp folder then go look for it and do not assume where you think it should be.

Its not a good idea to use the temp folder when the task is inactive for a long period of time; 12 hours in my case. You have no idea what may happen to the folder or data in that time period. Part of my system maintenance is to delete unused or not recently active files in the temp folder.

In any case, should you not be using the "..\BOINC\Data\slots\" folder for a task's temporary work files.

At a guess it doesn't seem likely, from the error message, that this causes an error.


However BOINC is set to leave the tasks in core while they are idle. I likely restarted the PC while the task was suspended. This could well have caused some corruption at the end of the file.
