With DHCP trace options enabled in their regression scripts, this core was seen. Issue is random not seen always. This was enabled in script for debugging in production network this will not be enabled by default hence the issue will not be seen. Its recommended to enable DHCP trace options only for debugging not otherwise.PR1771121

Low hold timer BGP sessions might flap post NSR switchover at 8000 BGP sessions scale in 23.4 release. PR1781414

On Junos OS Evolved platforms, when configuration of Decap filter action is on egress, commit error on both RE/PFE syslog messages is seen, however there is no service impact due to this issue. PR1793356

In case of primary-only inet6 address uses for re[01]:mgmt-0 interfaces, if there is inet6 address modification, the legacy inet6 address might still reside when do "ip -6 add show dev vmb0" under OS shell. The output of CLI command show interfaces re[01]:mgmt-0 shows the inet6 address correctly. PR1796934

On all Junos OS Evolved platforms, time-zone info changes to default UTC after upgrade is done with restart-upgrade. PR1803511

On all Junos OS Evolved platforms, while executing show log messages", error message sysctl kern.corefile not supported is seen which is introduced during daemon initialisation. PR1808481

On Junos OS Evolved platforms, when license gets expired, LICENSE_EXPIRED syslog is supposed to get generated which is missing. PR1808956

[evpn_vxlan] [evpn_instance] ptx10001-36mr :: JDI-RCT: Error message observed "RT : Mac Route install failed for rtt table index:452 Mac:0x5e000004 BD:170 ifl:4294967295 error:Generic failure" after performing disable ae member link on TOR device. PR1810348

On Junos OS Evolved PTX platform, the Border Gateway Protocol (BGP) session flap can be seen when inline Bidirectional Forwarding Detection (BFD) is configured under routing instance without loopback interface (lo0) leading to partial traffic drop. The issue is only seen when the interface is within the routing-instance. PR1811245

VRRP (Virtual Router Redundancy Protocol) will not work when VRRP group 0 is configured and specific Junos OS Evolved platforms PTX10001, PTX10003, PTX10004, PTX10008, and PTX10016 are working as primary.PR1816310

Segmentation fault on grpc timer thread (might be related to keepalive) #32085 grpc issue https://github.com/grpc/grpc/issues/32085 grpc stack needs to be upgraded to 1.53 or later. PR1722414

In Junos Evolved OS, during scaled configuration commit, Configd daemon in UI-infra is taking more time to process the commit. To optimise the processing time, most likely there will be design change required. There is no LKWR/pass instance. Also based on the configuration scale and the time taken for the commit to complete, it seems that this is a Day-1 issue.PR1701214

The request routing-engine login other-routing-engine command might fail.PR1712705

On Junos OS Evolved PTX10000 platforms, the vmcore might be seen if any component is forcefully removed from the PCI (Peripheral Component Interconnect) bus. PR1739142

On all Junos OS Evolved platforms, when MPLS (Multiprotocol Label Switching) statistics is configured without LSP (Label-Switched Path) configuration, the rpd process will crash and impact the routing protocols. This leads to traffic disruption due to the loss of routing information.PR1698889

On all Junos OS Evolved platforms, a memory leak is observed in the traffic engineering database (TED) when the inet table is not cleaned up after routing instance deactivation. PR1701800

On all Junos OS Evolved PTX platforms, the fwstatsd process will crash when openconfig-NI filter last term is only routing-instance action with no IPv4/IPv6 match. The process crash will impact show commands and openconfig state sensor support. PR1788695

ISIS TLV holds a maximum of 255 bytes of information per TLV. TLV contains data that has more than 255 bytes, current RFCs and drafts don't specify how to deal with multiple TLVs of same prefix. Hence it is advisable to associate bier subdomain to different lo0 TLV size exceed more than 255 bytes. It is not possible to define how many Bier subdomain will fit for given lo0 since it depend on other applicable subtlv associated with prefix. It is recommended to have advance planning/calculation before putting multiple bier subdomains under a single lo0 address. IS-IS TLV size exceeds 255 bytes, router behavior is undefine and may lead to multiple network issues. PR1776786

If its a scaled configuration with some configuration groups containing both wildcard and non-wildcard configuration, then the time it takes to commit the configuration is high. If upgrade is performed with this scaled configuration, then initial commit after upgrade might timeout and lead to a corrupt databases which could lead to mustd crash. To avoid this problem, move the wildcard configuration to another group.PR1804515
