Hi, could you help provide detailed steps to reproduce this issue?

CatherineF-dev commented 6 months ago

Also, could you try latest KSM version to see whether it's still having this issue?

Hi @gitlilei2019, could you help find which KSM version starts having this issue, if you're available? Thx

This problem is occasional, and sometimes curl ip: 8080/metrics may get stuck. But this problem has always existed, from version 2.4.2 to version 2.10.0, it was collected in "kube_persistentvolume_info" indicator will freeze for a few seconds, but it can still be executed in the end.
