Issue/Introduction

Since upgrading to Spectrum and NetOps 21.2.8 we have experienced issues with OneClick hanging and client disconnects.  We have seen where the OneClick process and sometimes the WebTomcat process consumes 100% cpu.  All of the clients hang and we are unable to use the OneClick console.

Cause

There was a threading issue with the Tomcat client configuration.
