1427075 VC split after network topology changed
Product-Group=junos
In Virtual Chassis scenario, when the interfaces flaps or VLAN configuration is changed frequently, the network topology will be changed accordingly, then CPU utilization will be dramatically increased to very high within a short time, which might cause the failure of essential communications between VC master and members. When the failure happens, FPC will automatically restart. As a result, VC is split and traffic is lost.
PR Number Synopsis Category: QFX Access control list
1403001 Filter install will be failed due to no resource
Product-Group=junos
QFX5120 will show as "No resources for operation " during installing filter QFX5120 switches with VXLAN configured, user configured ACLs are limited to only one type (iRACL, iVACL or iPACL). But in this case there is only IPACL no other filter config

PR Number Synopsis Category: QFX Access Control related
1515972 "dot1x" memory leak
Product-Group=junos
Memory leak is seen in 'dot1xd' daemon when no 'dot1x' is configured. Memory leak is seen for the allocation while creating socket from 'dot1xd' daemon to 'authd' daemon. If 'authd' is not running , 'dot1xd' daemon tries to connect to 'authd' periodically and every time it was allocating memory for string "/var/run/authd_control" for socket creation. The memory does not free in this scenario and we see memory leak for string "/var/run/authd_control". There will be no service impact to other services/daemons other than dot1x.

Product-Group=junos
On QFX10002/QFX10008/QFX10016, on the interfaces which map to h/w stream 0, if enhanced transmission selection (ETS), which in JunOS implementation is Hierarchical port scheduling configurations, change while high rate traffic is flowing, the chip might be wedged, thus no traffic flow is seen. Hierarchical port scheduling is the Junos OS implementation of enhanced transmission selection (ETS), as described in IEEE 802.1Qaz.
PR Number Synopsis Category: Internet Group Management Protocol
1520059 Packet loss might be observed while verifying traffic from access to core network for IPv4/IPv6 interfaces
Product-Group=junos
On EX2300-48T/EX2300-48P/EX2300-48MP, packet loss may be seen when L3 IPv4/IPv6 interface and route related configurations with IPv4/IPv6 unicast stream are configured. This issue might cause traffic drop. This issue happens if two different NH(Next Hop) IDs are programmed in the Hardware for same route but only one entry is maintained in the software.This issue is specific to 48 port EX2300 platforms and will not occur on other 12/24 ports EX2300, such as EX2300-24T, EX2300-24P, EX2300-24MP.
PR Number Synopsis Category: Kernel software for AE/AS/Container
1474300 A new aggregated Ethernet member interface for a static LAG bundle is installed in the FIB even though the micro- BFD session is down.
Product-Group=junos
On all Junos platforms, if a static Link Aggregate Group (LAG) is configured, and Bidirectional Forwarding Detection (BFD) is enabled on the LAG which is also called as micro BFD, a newly added member link might start to forward traffic immediately when the configuration change commits even though its micro BFD session is still down, for example, add a new member interface only on single end, and the remote member interface is disabled or not added. Therefore, traffic loss might be seen due to this issue.
PR Number Synopsis Category: jdhcpd daemon
1525052 The memory leak in jdhcpd might be seen if access-profile is configured under "dhcp-relay" or "dhcp-local-server" stanza
Product-Group=junos
With access-profile being configured under "forwarding-options dhcp-relay" or "system services dhcp-local-server" stanza, there might be memory leak in jdhcpd when DHCP request is processed. The leaked memory size for each processing will be the number of bytes equal to the length of the access profile.

PR Number Synopsis Category: Multiprotocol Label Switching
1517018 The rpd might crash after upgrading Junos software release from pre 18.1 to 18.1 onwards
Product-Group=junos
On all Junos platforms, the rpd might continuously crash after upgrading Junos software release from pre 18.1 to 18.1 onwards while graceful-restart and RSVP/static LSP are configured. This is because there is a change in the data structure written to the restart db file from 18.1 onwards. So, when rpd comes up and tries to read the restart db file written by pre 18.1 release image, the rpd might crash.
PR Number Synopsis Category: Multicast Routing
1443713 PIM (S,G) joins might cause MSDP to incorrectly announce source active messages in some cases.
Product-Group=junos
In the event of a network running: 1) a first-hop PIM router also being a rendez-vous point (RP); and 2) anycast RP in conjunction with MSDP; and 3) any-source multicast; and 4) a PIM last-hop router sending an (S,G) join when there is no traffic in the network matching the source and group, the first-hop RP will incorrectly send MSDP source-active messages to other MSDP peers. In other cases such as when the RP is not the first-hop PIM router, the traffic source needs to originate packets before the RP would originate MSDP source-active messages.
