| SVAPAR-96777 | 8.6.1.0 | Policy-based Replication uses journal resources to handle replication. If these resources become exhausted, the volume groups with the highest RPO and most amount of resources should be purged to free up resources for other volume groups. The decision which volume groups to purge is made incorrectly, potentially causing too many volume groups to exceed their target RPO |

| SVAPAR-98567 | 8.6.0.0 | In FS50xx nodes, the TPM may become unresponsive after a number of weeks' runtime. This can lead to encryption or mdisk group CLI commands failing, or in some cases node warmstarts. This issue was partially addressed by SVAPAR-83290, but is fully resolved by this second fix. |

| SVAPAR-99273 | 8.5.2.0 | If a SAN switch's Fabric Controller issues an abort (ABTS) command, and then issues an RSCN command before the abort has completed, this unexpected switch behaviour can trigger a single-node warmstart. |
