Ongoing thread activity logging threshold reached for connection handler
Sometimes we catch warning in the system repository log on the central node:
Ongoing thread activity logging threshold reached for connection handler 'Repository API REST Server'. Number of active threads: 60 ActivitySnapshotID: b25e1652-d5d5-44fe-99d8-aec03094aab6
After that Repository.exe process start to consume CPU and system slow down. Sometime restart all the services help. But in some cases we need to restart all cluster nodes to resolve issue.
