@dgsudharsan please have a look at these PRs: Also, the original code is working and very likely that you are using old codebase: P.S: the suggested fix doesn't assume warm/fast boot scenario |

What I did
Optimized teamd cleanup to handle scaled portchannel configuration scenarios.
Why I did it
A process per portchannel exists in teamd which needs to be cleaned up on exit so remove port channel flow is handled. In the current logic this is done one by one. So in case of scaled configurations not all port channels get cleaned up resulting in some portchannel entries left stale.

In the above example port channels after 58 (from the map) are not cleaned up even after 60 seconds. Each system command called from the process is costly and it takes a lot of time when the scale is high.
The netlink messages for stale portchannel come up during the initialization which if ordered differently might result in STATE_DB entry being removed
