Description	On Juniper Networks Junos OS and Junos OS Evolved platforms with EVPN configured, receipt of specific BGP packets causes a slow memory leak. If the memory is exhausted the rpd process might crash. If the issue occurs, the memory leak could be seen by executing the "show task memory detail \| match policy \| match evpn" command multiple times to check if memory (Alloc Blocks value) is increasing. root@device> show task memory detail \| match policy \| match evpn ------------------------ Allocator Memory Report ------------------------ Name \| Size \| Alloc DTXP Size \| Alloc Blocks \| Alloc Bytes \| MaxAlloc Blocks \| MaxAlloc Bytes Policy EVPN Params 20 24 3330678 79936272 3330678 79936272 root@device> show task memory detail \| match policy \| match evpn ------------------------ Allocator Memory Report ------------------------ Name \| Size \| Alloc DTXP Size \| Alloc Blocks \| Alloc Bytes \| MaxAlloc Blocks \| MaxAlloc Bytes Policy EVPN Params 20 24 36620255 878886120 36620255 878886120 This issue affects: Juniper Networks Junos OS 19.4 versions prior to 19.4R2; 20.1 versions prior to 20.1R1-S4, 20.1R2; Juniper Networks Junos OS Evolved: 19.4 versions; 20.1 versions prior to 20.1R1-S4-EVO, 20.1R2-EVO; 20.2 versions prior to 20.2R1-EVO; This issue does not affect: Juniper Networks Junos OS releases prior to 19.4R1.
