Data Node "lag target notified", error="send target timeout, vchannel=..."

[xiaobingxia-at]

Hello team, I consistently see the following errors in data node logs:
[2024/11/07 15:43:47.620 +00:00] [WARN] [msgdispatcher/dispatcher.go:244] ["lag target notified"] [pchannel=milvus-5m-partitions-rootcoord-dml_7] [isMain=true] [error="send target timeout, vchannel=milvus-5m-partitions-rootcoord-dml_7_453757715823437281v0, timeout=3s"]
May I know what's this error about? Should I worry about that? If yes, how should resolve the bottleneck?

Thank you!
