Due to a the disk failure reboot support was not added for dual disk scenario, hence system was not booting in case of disk failure on sdb (the other disk) on QFX platform. PR1800862

On Junos QFX5100 and EX4600 Platforms, high storage Utilisation is observed in /var/log due to uncompressed UKERN_GBL.log file. This can lead to low storage warnings and potential write errors for other system logs during that period. PR1804090

On all Junos QFX5000 platforms, traffic loss happens and the layer 3 interface cannot be deleted when many routes use the same layer 3 interface. QFX5000 is encapsulating the packets with the wrong DMAC(destination MAC ) and VNID(virtual network identifier) for a few IP addresses after disabling the interface. PR1808550

The traffic is still getting forwarded to all the interfaces mapped with concerned VLAN even after unknown-unicast-forwarding configuration statement is enabled on all Junos QFX10000 platforms, but it is allowed to be configured, so the command is disabled to avoid misconfiguration. PR1810120

On all Junos QFX5000 platforms, with ECMP (Equal Cost Multi Path) configured, when there is any routing protocol change (like ISIS cost metric change), the protocol traffic on the network is dropped. PR1823601

The PTX10008, PTX10002-60C, or QFX10002-60C platforms might not send back ICMPv4/v6 reply packets properly due to defects leading to misprogramming of hardware. Ping with v4/v6 from another device to the PTX10008, PTX10002-60C, or QFX10002-60C platform will fail. PR1827286

Graceful Routing Engine Switchover (GRES) not supporting the configuration of a private route, such as fxp0 , when imported into a non-default instance or logical system. Please see KB https://kb.juniper.net/InfoCenter/index?page=content & id=KB26616 resolution rib policy is required to apply as a work-around. PR1754351
