WARNING: Failed to create work directory [...../cai/CASoftware/CCS/apache-tomcat-8.5.30/work/Catalina/localhost/castylesr5

The system defined /work directory had insufficient space. This is dynamically allocated by Tomcat from the system defaults. Insufficient space caused the problem with deploying castyles.
Web Viewer 12.1 for USS, Build 190
Apache Tomcat 8.5.34
REGION=0M was specified in the Tomcat JCL. This allows Tomcat to use all available space, which was insufficient. Increase the size of zfs to allow more space to be allocated for Tomcat.
