1599094 The l2ald process may crash due to memory leak when all active interfaces in a VLAN are unstable
Product-Group=junos
When none of the constituent active interfaces on a VLAN is stable, memory leak may occur which might eventually lead l2ald to crash. No memory leak will be seen if one or some constituent interfaces are flapping but the VLAN has at least one active stable interface overall.
1615269 The l2ald process might crash in EVPN scenario
Product-Group=junos
On all MX and QFX platforms, memory corruption might happen when the IRB interface configuration is changed or MAC is added/deleted from VLAN MAC list of a Bridge Domain in an Ethernet Virtual Private Network (EVPN) scenario. The l2ald process crashes and multiple cores are generated. This is a rare issue and it recovers automatically.
PR Number Synopsis Category: lacp protocol
1599029 Uneven traffic distribution might be observed between member links of LAG
Product-Group=junos
On PTX Series routers with LAG scenario where a prefix is advertised by two devices that are connected to the same upstream device, if the traffic with explicit null MPLS label from the upstream device to this prefix is shifted away from one of the devices by any means (like withdrawing the route advertising or disconnecting all its LAG links to the upstream device), the uneven traffic distribution might be seen on a few member links of the LAG on another device. This is due to an improper hash algorithm for LAG, which might cause performance degradation.

1597066 Major alarms on all FPCs in chassis might be seen after some time from bootup
Product-Group=junos
On MX10008/MX10016 platforms, the Flexible PIC Concentrator (FPCs) may get into Major alarm state which would mean Packet Forwarding Engine 0 (PFE0) disables operation after some days from start of the chassis, for instance bootup.

Product-Group=junos
In a very rare situation, all ports from the same pfe going down may cause mqchip_disable_ostream timeout. When this error is seen, it is possible to have a temporary host loopback path wedge error and trigger disable-pfe. The wedge can be cleared by itself but the disable-pfe needs a FPC reboot to recover. After the fix, mqchip_disable_ostream timeout might be still seen but it won't trigger wedge and disable-pfe.

1551193 VM might crash if file is shared between host operating system and guest operating system using virtFS
Product-Group=junos
On Virtual Machines (VM) based platforms running Junos images, file might not be shared between host operating system and guest operating system via Virtual Filesystem (virtFS). When this issue happens, device might be restarted.
1563647 Memory corruption of any binary in /usr/bin/ or /usr/sbin/ may be triggered when a recovery snapshot is being copied to the OAM volume or system while it's in heavily stressed condition
Product-Group=junos
Memory corruption of a binary from /usr/bin/ or /usr/sbin/ directory can occur if such binary is invoked when a recovery snapshot creation is in progress. The exact symptoms will be different depending on the exact binary and JUNOS version - some programs will show an error, and some programs will crash every time it is executed. Such memory corruption will be persistent until the affected Routing Engine is restarted. Please refer to TSB17954 (https://kb.juniper.net/TSB17954) for further details. In addition to recovery snapshot, a device reboot could also be a possible trigger when the system is under heavier read operations across the mounted packages.
1602005 Upgrade might fail when upgrading from legacy release
Product-Group=junos
On all platforms while directly upgrading from Junos with FreeBSD 6 (e.g. 15.1X49 or before) to the affected releases, the system will check the USB connection. The upgrading will fail if there is no USB device detected during the upgrading process.

1610295 MAC move or MAC flap may be triggered in the QFX5k VC environment
Product-Group=junos
On all QFX5k platforms with VC (Virtual-Chassis) setup, IGMP (Internet Group Management Protocol) control packet received on a port in the backup (backup-RE) unit is forwarded back to the same port whereas split horizon is not working. Due to this, we might observe MAC (Media Access Control) move or flap. The workaround is to change the mastership between FPCs.

1617830 Traceroute packets might get dropped in SFW service-set when other service-sets with asymmetric traffic processing are also enabled on the same MS-MIC/MS-MPC
Product-Group=junos
When there are service-sets which are configured with knob "enable-asymmetric-traffic-processing" along with other CGNAT(carrier grade NAT) or SFW(stateful firewall) service-set, traceroute packets might get dropped on those even when the ICMP works for ping operation or otherwise. This can happen on ms- interfaces, i.e. on MX devices where multiservices-MPC (modular PIC concentrators) like MS-MPC or MS-MIC are installed. The initiator of the traceroute will not receive any error messages informing them about the failure.
