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

Error message

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

What it means

computeJobAllocs fetches all allocations for the eval's job via StateStore.AllocsByJob to reconcile them. A state store error aborts processing with this wrapped error. This is about the lookup failing, not about allocs being absent.

Solutions

1. Read the wrapped underlying error to identify the root cause
2. Retry — failed evals are reprocessed by Nomad
3. Check server/raft health; restore from snapshot if corruption is suspected
4. Reduce server load or upgrade Nomad if the issue recurs

nomad job status <job-id> // confirms job allocs are retrievable and cluster is healthy

// Inspect the wrapped error in server logs; rely on eval retry
nomad eval list | grep -i failed

When it happens

Trigger: StateStore.AllocsByJob(ws, eval.Namespace, eval.JobID, true) returns an error during computeJobAllocs — memdb failure, closed snapshot, index iteration error.

Common situations: Nomad server state store instability, resource exhaustion, raft restore, or version-specific state store bugs.
