Too many levels of symbolic links

CentOS 7.7 introduced an update to systemd that changed how systemd opens symbolic links. The update conflicts with out-of-date kernels on OpenVZ or Virtuozzo environments. Systems affected by this issue can produce Too many levels of symbolic links and Can't open PID file errors in cPanel & WHM service startup logs.

Consider transferring your cPanel & WHM accounts and configurations to a new environment if your VPS service provider is limited in its capacity to update your operating system to a modern kernel.

Transfer instructions are available here: How to Transfer Accounts and Configurations Between cPanel Servers. Hyperscale Cloud Providers such as DigitalOcean are a good choice if you need to quickly transfer cPanel & WHM accounts and configurations to a new environment in a hurry.
