I\'ve been running sulphur 4.22 on a single XP pc for about 3 weeks with no problems. Feb.18th I wanted to exit BOINC to run a backup of all files but it wouldn\'t close so I ended the 2 sulphur processes shown as active in the Task Manager. BOINC closed. I ran my backups and tried to restart BOINC (using boincmgr.exe as usual) The program window appears and the messages look normal indicating that it has started but the 2 sulphur PROCESSES don\'t appear in the Task Manager (even after a cold start) and the cpu usage indicates 0% instead of the usual 100% in Task Mgr. When the screen saver comes up it is the one that says BOINC is idle. I poked around in the files and found in \"stderrdae.txt\" the following message:\"2006-02-18 08:37:05 [climateprediction.net] Unrecoverable error for result sulphur_ihcz_100862307_1 (Incorrect function. (0x1) - exit code 1 (0x1))\" whose time stamp is very close to the time I killed the 2 processes. Could this just be a colossal coincidence or did my actions cause the error? Regardless, can anyone help me get BOINC active again and do it without losing 3 weeks of data? Would really appreciate any assistance. Thanks.

You may well have caused the crash, or it could be that it crashed just before your attempt to shut down BOINC.

While it is now considered safe to just kill BOINC, the most safe way is to menu/Suspend, wait until the message in the Work tab says Suspended, and THEN exit.

The only way to get back the model on which you were working, is from a previous backup.
I interpret your post as meaning an entire hard disk backup.
If it\'s possible to just extract the BOINC folder from a previous b-u, then do so, first off deleting the current BOINC folder.

Post again if I\'ve gotten the situation wrong.

I have had similar problems, especially when starting boinc and finding its in idle mode.
To get boinc restarted and working, I first close the program by right clicking on the system tray and then pressing exit.

Then I restart boinc via the start menu, which usually produces an error message about not being able to connect. Click \"OK\" and close boinc down down a second time via the system tray.

Finally restart boinc again, and all the problems seem to have corrected themselves.

Not very scientific I know,but it works every time. It always follows the same routine.
Hope this helps

This seems similar to my situation. Running XP Home I experienced a blue screen a couple of days ago. BOINC was NOT running. Despite this, after a restart BOINC couldn\'t/wouldn\'t see the 78% completed project I have on my machine. After connecting to climate prediction my computer downloaded a new model. Can I pause the new model, find and complete the old model, and then restart the new. How?

Suspend, wait, Exit BOINC.
Copy the BOINC folder to somewhere safe.
Delete the \'working\' BOINC folder.
Copy the previous backup folder, (with the \'old\' model), and paste it to where the deleted folder was.
Re-boot, to remove everything from memory, and also to restart BOINC.

Set the project, in the Projects tab, to No new work.

When the old model has finished and uploaded, repeat parts of the above:
Delete the BOINC folder.
Copy the backup with the \'new\' model, and paste it to where the \'working\' BOINC folder was.
Reboot.

edit
With the new TCMs, BOINC version 5.* is required.
223Megs of ram is insuffient for running the model. They use about 380Megs, and the recommended minimum is 512Megs.
