Description
This happened in qr2hi: (I don't know if this exceptions are the cause of the manager being wedged or not. ) I restarted the service and the nodes were created.

The last traceback you pasted, the one you based the subject on, is #6225.
The ActorDeadError above that is more interesting, that's almost always going to be a problem. More logs before that would be good to see.
- Description updated (diff)
yes... I guess the fingerprint it's irrelevant. Probably we should not transform that traceback into a WARNING or something.
I added a log that has the ActorDead. moved to Arvados private just because it has a log.
- Project changed from 35 to Arvados
- Subject changed from [Nodemanager] GCE returns "ActorDead" to [Nodemanager] 'unicode' object has no attribute 'id'
The original error was aaallllll the way back here:

From this point on, the daemon actor was dead. The traceback in the description only happened after someone tried to stop the process, and the stopping process failed because the daemon was already dead--the exception came from the signal handler.
- Subject changed from [Nodemanager] 'unicode' object has no attribute 'id' to [Nodemanager] On GCE: 'unicode' object has no attribute 'id', where we should have a NodeSize
This is a bug introduced by #8872. The node returned by search_for doesn't have its size attribute fixed.
- Status changed from New to In Progress

Related to this, perhaps on_failure() should kill self on all unhandled exceptions and not just certain ones? Currently the policy is to handle recoverable exceptions before it gets to on_failure(), so once an exception gets to on_failure() it means an actor is going to die unexpectedly, which generally results in node manager getting wedged. (Filed a separate report #8932)
The fix in 8912-node-manager-patch-nodes-wip 8db9ad8 LGTM.
- Status changed from In Progress to Resolved
- % Done changed from 0 to 100
