Web Viewer 12.1 Failed, Bounced Tomcat to Resolve

Products

• CA Output Management Web Viewer

Issue/Introduction

This morning I logged on to see a bunch of emails saying the Web Viewer was down. 
Users saw the 'Can't reach the page' error. 
I logged onto the linux server and issued ps command and it appeared the viewer was active.  I shutdown tomcat, restarted tomcat and that resolved the issue. 

Environment

Release : 12.1

Component : CA OUTPUT MANAGEMENT WEB VIEWER FOR ALL PLATFORMS

Resolution

There were definite CCI connection (pipe broken)  errors in the Catalina log.  There was apparently a network problem that could not be resolved until Tomcat was recycled.
