Unable to launch the Spectrum OneClick WebApp

Products

• Spectrum
• Network Observability

Issue/Introduction

After clicking OneClick WebApp link, a new tab opens and we see "Starting the application" for a split second and then it kicks off and goes back to the OneClick home page. I've bounced the services on the OneClick server and also rebooted, but no changes. 

Environment

Release : Any

Component : Spectrum OneClick WebApp

Cause

In this instance, a check of the $SPECROOT/webtomcat/bin/logs/webswing.log files shows the following error:

2021-09-01 11:07:40,396 ERROR [Webswing Process Handler] (SwingProcessImpl.java:322) [oneclickwebapp_anonym_1dccc3be89d2_1630494460186] java.io.IOException: No space left on device
