took 6.413 days & completed with an error - what a waste - I won't run another 1 of these on this computer!

Boinc aborted the task with 'Maximum elapsed time exceeded' as it took 10 times longer than it should, Have you freed a CPU core to stop the GPU apps being slowed down?

Maximum elapsed time exceeded

That host is running a particularly old CAL driver of 1.4.1417, this equates to Cat 11.6 and should have OpenCL runtime of 650.9 (assuming they haven't become mismatched), this was an SDK 2.4 driver/runtime:

ATI Driver Version Cheat Sheet

It is quite possible that your host has a too old driver/OpenCL runtime for the projects apps, They may have been built with SDK's as recent as SDK 2.7 or 2.8

Very rarely I get BRP5 tasks

Very rarely I get BRP5 tasks that runs "forever". I abort them when I check the boinc manager and see tasks taking waaaay too long. Like this one:

Only happens on my ATI card, never seen it on a Nvidia card.

I also see this from time to

I also see this from time to time, there is no need to abort the stuck/overly long running task as a simple suspend/resume of the task will get it going again from the last checkpoint and in my case they will always then run to completion and validate.

I concur that this only happens with (my) AMD cards and not NVidia, don't know why but if you can keep a regular eye on your hosts you can spot the problematic tasks without wasting too much time and as I have said a simple suspend/resume sorts it out.

Mark, that host is very slow.

Mark, that host is very slow. But it shouldn't be this slow, so I agree with Claggy: try to update your driver. That "E-300 APU" is just a system-on-chip with the codename "Brazos", so you should be able to get drivers from AMD just fine, even if your laptop/small box manufacturer doesn't provide any update. Which would not be unusual, normally they'd rather sell you a new system than make your current one work properly.
