I was hoping that this had ceased to be an issue and running tasks under WINE that seems to be the case, but running native linux tasks even if I suspend computation, wait a few minutes file exit I seem to lose a task about one in three times.

I will revert to waiting till no tasks are present before updating kernel. Interested to know if others still experiencing this? Is it more of a problem during kernel updates or is it any shut down and restart? Not lost any if I hibernate.

How do you suspend computation? Per task, project or at all? Suspending each task seems to work better for me.

I usually suspend per task and then globally, resuming in reverse order. It seems to be a particular issue when the kernel is updated. Restarting at other times seems to drop the failure rate to about one in ten but data a bit sparse because I don't restart that often except when kernel needs updating.

Dave, I've had better luck with the following global compute preference checked:
"Leave non-GPU tasks in memory while suspended" = yes

If that is disabled on your account, try enabling it and see if that improves things.

Thanks for adding that. I have in fact had "Leave non-GPU tasks in memory while suspended" enabled on my boxes for many years. The measures I have outlined are in addition to that.

Not sure whether something has changed in the tasks or in more recent incarnations of BOINC but of late even when I have had restarts due to power failure, (electrician turning mains off without warning) I haven't lost tasks to it. Something has improved but I don't know what.(Over I would guess last 9 months to a year is an approximate time for the change.)
