Affected: Grafana Tempo, Grafana Enterprise Traces (GET), Red Hat Multicluster Global Hub 1.3.4, Red Hat Multicluster Global Hub 1.4.5, Red Hat Multicluster Global Hub 1.6.5, Red Hat Multicluster Global Hub 1.7.0, Red Hat multicluster global hub 1.5.3, Red Hat Logging Subsystem for Red Hat OpenShift, Red Hat Multicluster Global Hub, Red Hat Advanced Cluster Management for Kubernetes 2 and 6 more

Tempo queries with large limits can cause large memory allocations which can impact the availability of the service, depending on its deployment strategy.

Mitigation can be done by setting max_result_limit in the search config, e.g. to 262144 (2^18). Alternatively, automatically restart the service.
