To recover the respective RE needs to be restarted manually.\n\nThis issue only affects IPv4 but does not affect IPv6.\nThis issue only affects TCP sessions established in-band (over an interface on an FPC) but not out-of-band (over the management ethernet port on the routing-engine).\n\nThis issue affects Junos OS Evolved:\u00a0\n\n  *  All versions before 21.4R3-S9-EVO,\n  *  22.2 versions before 22.2R3-S4-EVO,\n  *  22.4 version before 22.4R3-S3-EVO,\n  *  23.2 versions before 23.2R2-S1-EVO,\n  *  23.4 versions before 23.4R2-EVO."
