Issue

After upgrading to Tableau Server 10.4.2 or 10.3.6, high CPU usage is observed by the Vizqlserver process and log files exhaust disk space. 

Additionally, you notice that the following error repeats in the VizqlServer log files:

"Invalidating Layout for Worksheet"

Environment

Tableau Server 10.4.2 or 10.3.6

Resolution

Option 1

As a Tableau Server Administrator, upgrade Tableau Server to version 10.4.3 or 10.3.7.  See Upgrading Tableau Server for more information. 

Option 2

As a workaround, run frequent tabadmin cleanup tasks to keep the disk space from filling up.

You can script the running of tabadmin cleanup and use Windows Task Scheduler to schedule regular execution. 

Cause

This is due to a known issue, ID 728756, which has been resolved in Tableau Server versions 10.4.3 and 10.3.7 and later.
