Change:
What happened: i wrote a shell then the kubelet's RSS increases continuously and does not release i make some trace and found some watched objects have never been released even these objects have not existed in real word i notice the fucntion readEvent is producer for these abnormal objects and print the length of every eventsome of which is beyond the length of buf even when i increase the array by 10 timesthe problem is still there and the limits are broken through again and again. so i realized the process of reading cannot be blocked. now i a queue for the buf of every inotify event and another goroutine to consume the queue. everythings seems good for now. What you expected to happen: fixed the bug How to reproduce it (as minimally and precisely as possible): running the shell : Anything else we need to know?: Environment: Kubernetes version (use ):1.17.9 Cloud provider or hardware configuration: OS (e.g: ):Kernel (e.g. ):Install tools: Network plugin and version (if this is a network-related bug): Others:

I didn't repeat the question. Is there a way of stable recurrence? Thx!
you could use the shell i'v paste above, or make "add" more faster than "delete".....
