  • On all Junos OS Evolved platforms, the rpd crash might be observed in a rare scenario when the configuration statement no-propagate-ttl is configured under the apply-groups along with link protection for static LSP. This issue is seen when activating or deactivating the MPLS configuration and might lead to traffic loss. PR1528460

Network Management and Monitoring

  • A memory leak in the mib2d and snmpd processes might result in SNMP being unresponsive to SNMP queries on platforms running the affected Junos OS Evolved image. PR1543508
