19.3R2-S1 - List of Fixed issues

PR Number Synopsis Category: Marvell based EX PFE L2
1474808 Continuous dcpfe error messages and eventd process hogged might be seen on EX2300 VC scenario
 
On EX2300 VC scenario, when host path packets are flooding through internal HG (higig) port, it might generate some dcpfe error messages which are harmless and eventd process hogged might also be seen. And it also might cause high CPU utilization which might affect protocol traffic.
PR Number Synopsis Category: EX2300/3400 platform
1477165 EX3400 me0 interface might remain down
 
The me0 interface of EX3400 does not come up when connected to 100m speed interface.

1432078 Shaping does not work after the reboot if "shaping-rate" is configured.
 
On QFX5110, QFX5100 and EX4600 platforms, if "shaping-rate" is configured, the shaping feature might not work after a reboot. The service might be impacted as the traffic cannot be rate limited.
PR Number Synopsis Category: QFX PFE L2
1462171 The LLDP function might fail when a Juniper device connects to a non-Juniper one
 
On EX/QFX platforms with STP disabled, the LLDP function might fail when a Juniper device connects to a non-Juniper one. In this scenario, the LLDP PDU with destination MAC 01:80:c2:00:00:00, which is one of the three reserved MAC addresses for LLDP in IEEE 802.1AB, will be ignored by Juniper LLDP process, and this causes the LLDP function failure. This issue has service impact.
1474142 Traffic might be affected if composite next hop is enabled
 
On QFX5000 and EX4600 platforms with composite next hop enabled, traffic loss would occur when deleting leaked routes with composite next hop.
PR Number Synopsis Category: QFX L3 data-plane/forwarding
1455547 The coredump might occur during adding/removing EVPN Type-5 routing instance
 
On QFX platforms, the coredump might occur during adding/removing EVPN Type-5 routing instance. The EVPN route would be corrupted and traffic/service impact appears if hitting the issue.
1477073 GRE transit traffic does not forward in VRRP scenario
 
On QFX5110 platforms, GRE transit traffic might be dropped when sending GRE tunnel packets with the destination MAC as VRRP MAC. It has a traffic impact.

1442902 The CPU utilization on rpd spins at 100% once the same external BGP route is learned in different vrf tables
 
With "advertise-external" knob configured in BGP and "auto-export" knob configured in vrf, once the same external bgp route is learned in different vrf via the import policy, the CPU utilization on rpd will spin at 100% immediately.
1466709 BGP peers might flap if the parameter of hold-time sets small
 
On all Junos platforms with BGP enabled, the hold timer is still running when the session is to processing BGP updates to peers, but the keepalive messages which BGP peer sends might be skipped. If the BGP updates in handling cannot be completed within the hold timer (e.g., manually sets the hold-time to 3s), the BGP peer flaps might be observed.

1451215 Main chassisd thread at a JNS GNF could experience stalls upon GNF SNMP polling for hardware-related OIDs
 
- Chassisd main thread stalls could be seen at a JNS GNF upon GNF SNMP polling for HW-related OIDs (e.g. ones from jnxBoaAnatomy MIB). - If a GNF chassisd main thread stalls are ongoing and the GNF is restarted, then a service MGD process at the BSYS could start spinning at 100% CPU. This MGD process won't terminate by itself and will be consuming 100% CPU even when the GNF is back online.

1475036 Memory leak leading to MPC10E line card restart
 
The "sensord" daemon on MPC10E linecards leaks memory at a rapid rate. The memory leak results in total memory exhaustion. Consequentially, all control traffic transiting all PFEs on the MPC10E stalls. Shortly after this stall the MPC10E may restart. If the MPC10E restarts there will be no core dump recorded. The rate of memory leak varies depending on the number of populated optics in the MPC10E and on the number of MPCs installed in the system. Typically the MPC10E will restart in this manner after 15 days of operation. [TSB17705]

1471191 The rpd process might crash during shutdown.
 
The rpd shutdown process such as clean up of scale configuration and rolling it back with LDP configured might cause rpd to crash. Rpd shutdown rarely happens during normal operation. It is widely used for testing purpose. Rpd crash may result in traffic loss.
PR Number Synopsis Category: mc-ae interface
1479012 MC-AE interface may be shown as unknown status if adding the sub-interface as part of the VLAN on the peer MC-AE node
 
If adding the sub-interface as part of the VLAN on the peer MC-AE node while its corresponding MC-AE interface is still not configured to be part of the VLAN, the status of the MC-AE interface might be shown as unknown. It might have an impact on the traffic as the colour of the MC-AE interface could not be updated correctly.

1471372 Sudden FPC shutdown due to hardware failure or ungraceful removal of line card may cause major alarms on other FPCs in the system
 
On the MX10008/MX10016 platforms, If the FPC line card gets offline due to power failure or FPC Line card is removed from the chassis without prior offline of the card, other FPC line cards in the system will report fabric failures and fabric self-ping failures. The fabric self-ping failure will invoke disable-pfe action. Once PFE is disabled due to disable-pfe action, the line card needs to get restarted to recover.

PR Number Synopsis Category: security-intelligence feature on SRX
1472926 SRX PFE memory might be used up if the security intelligence feature is configured
 
On all SRX platforms, if the security intelligence feature is configured, PFE memory leak might happen while handling HTTP Uniform Resource Identifier (URI) and the memory might be used up. The memory leak size depends on the length of the HTTP URI request. The HTTP URI request length can be a few bytes to a few KB. If the average length of URI is 100 bytes, then the memory leak is 100 bytes for each request. If the available memory is consumed, the PFE has to be restarted manually. The traffic might be impacted during that time.
