failed to get allocs for job '%s': %v

Error message

failed to get allocs for job '%s': %v

What it means

Returned by SystemScheduler.computeJobAllocs when AllocsByJob fails to fetch the job's existing (non-terminal) allocations. Reconciliation between desired and current state is impossible without them.

Solutions

1. Check server logs for the allocs query failure
2. The eval is retried automatically on the next pass
