So I am running boinc on a windows machine using the gpu. I have been getting wu in an error state with the stderr

Maximum elapsed time exceeded

anyone know what this means? It can not be speaking of the wu deadline since thats over 2 weeks away.

I now have 7 of these so I am curious as to what this is about and if there is any way to eliminate it.

When have you rebooted that machine the last time?

It looks like the CUDA tasks get stuck on your GPU. Are they showing any progress in the Tasks tab of BOINC manager when running?

Maximum elapsed time exceeded

anyone know what this means?

What it means is this:
Each task comes equipped with a 'runtime estimate' which is measured in FLOPs (FLoating point OPerations). It's the <rsc_fpops_est>64788201036261.297000</rsc_fpops_est> amount in the <workunit/> tags in client_state.xml file (my example given is from an Einstein task).

BOINC will check whether or not the application goes over this estimated amount, and if it does, the application is stopped and that error is given.

Another error similar to that is when <rsc_disk_bound>100000000.000000</rsc_disk_bound> gets exceeded, then the message is "Maximum disk space exceeded". Then the amount of disk space that the task should use up is too big.

Simply put:
If the task for whatever reason runs 10 times longer than the initial estimate (column "To completion")
BOINC aborts the task automatically as it decides that the task is hang/stuck.

(But why it happened to tasks with "Run time: 0.00" I don't know

Maybe because you just reached:
Consecutive valid tasks 11
