For the most complete and latest information about known Junos OS defects, use the Juniper Networks online Junos Problem Report Search application.

Application Layer Gateways (ALGs)

  • The srxpfe or mspmand process might crash if FTPS is enabled in a specific scenario. PR1510678

Class of Service (CoS)

  • The following error message is observed: GENCFG write failed (op, minor_type) = (delete, Scheduler map definition) for tbl id 2 ifl 0 TABLE Reason: No such file or directory. PR1476531

  • The MX Series routers with MPC1 Q and MPC2 Q line cards might report memory errors. PR1500250


  • When a dynamic list next hop is referenced by more than one route, it might result in an early deletion of the next hop from the kernel, thereby assigning the NH index as 0 (Next hop type: Dynamic List, next hop index: 0" in the output of the show route command). This would not result in a crash, but an early delete from kernel. As a workaround, restarting the routing solves the issue and the NH index gets reassigned properly. PR1477140
