Which version are you using on the WLC? and have you check the status of FANs ? from the description it could look like a fan issue.

The WLC using version is 8.10.171.0

Fan status is ok

I think maybe we need to restart WCL or update to the recommended version to fix it

   Good plan the older aireos based controllers should nowadays always use the last release available for the
  particular model : https://software.cisco.com/download/home/286312601/type/280926587/release/8.10.196.0
