The abandoning of tasks happens when the BOINC server 'thinks' that it has 'evidence' that the client has detached from the project and then re-attached again. This has affected a number of users in the past, but has proved extremely tricky to diagnose and resolve: not least, because most of the evidence resides in the server logs.
We did investigate one suspected case at Albert during credit testing, but that turned out to be a genuine 'detach' caused by hard disk failure - it is distinguished from reports like this one because no running tasks were left on the host computer (they were on the drive that failed...) to waste time and electricity. I would certainly welcome it if we could pair up a developer and a project administrator with access to server logs to investigate this problem and cure it at source. The checkpointing question is a matter for the project developers, and I'll leave it to them to respond via this list. >________________________________ > From: Luc A.
