根据您提供的日志，问题核心是出方向队列瞬时拥塞导致的丢包。丢包发生在 Ten-GigabitEthernet1/0/44端口的队列2，并关联到槽位1。丢包与恢复间隔约1分钟，表明是突发流量触发了端口的缓存队列上限。

请按以下步骤排查和解决：

检查端口流量与错误

在交换机上执行 display interface Ten-GigabitEthernet 1/0/44，重点关注：
- 最近5分钟的输入/输出速率：查看 Input/Output rate和 Last 5 minutes input/output rate，判断是否有流量突发尖峰。
- 错误计数：检查 Output方向的 Drops是否持续增长，确认丢包是否集中在队列2。
检查端口及对端配置
- 速率与双工：确认本端端口 Ten-GigabitEthernet1/0/44和对端设备端口均配置为自协商（默认）或强制为相同的速率、双工模式。不匹配是常见原因。
- 流控：检查是否启用了流量控制 flow-control。在突发场景下，启用流控可能有助于缓解丢包，但需两端都支持并开启。
检查物理层状态
- 执行 display transceiver interface Ten-GigabitEthernet 1/0/44检查光模块/电口的收发光功率、电压、温度是否在正常范围内。
- 尝试更换光纤/网线或光模块/电口模块，排除物理介质故障。
调整队列调度或进行流量限速（高级操作）
- 如果确认是特定应用（如备份、视频流）的突发流量导致，可以考虑在端口或全局视图下配置流量监管来平滑流量。
  
  # 示例：在接口下限制出方向流量为8Gbps（请根据实际需求调整） interface Ten-GigabitEthernet1/0/44 qos lr outbound cir 8000
- 或调整队列调度策略，为队列2分配更多带宽或采用WRR等调度方式。具体命令需参考设备手册和当前QoS配置。
监控设备整体状态

您已执行了 display device、display memory、display cpu，这是正确的。请确保：
- CPU利用率 (display cpu) 在正常范围（通常平均<50%），无持续高占用。
- 内存利用率 (display memory) 充足，无持续增长趋势。
