Describe the bug WKC installation is get failed

We are trying to install WKC, WSL. We are facing issues, 2 pods are continuously in loop of kill, start and pending loop(please refer attached screen shot). while investigation we found that there is a pod "zen-database-core-xx" restart on every few internal and it's having following error message in the log. not sure if there is a dependency wrt the issue. We are unable to install WKC currently using cp-deployer. May we get some help on this?

Fixed:

• Only a single KubeletConfig will be created (multiple KubeletConfigs not supported by MachineConfig)
• Dependent on OCP version, the KubeletConfig will include podPidsLimit
• Existing obsolete KubeletConfig is deleted if found
