Remediation

Vendor Workaround

Where possible, configure the indexer to run scanner workloads in isolated processes or containers so that a single scanner panic cannot terminate the shared indexer. Alternatively, deploy multiple indexer replicas behind a load balancer to reduce the blast radius of a single-process crash.
