If you have 10 or more SAS^® LASR™ Analytic Servers running in a non-distributed SAS Visual Analytics deployment, the software might stop responding when you attempt to perform one or more of these actions:

• Start a SAS LASR Analytic Server.
• Stop a SAS LASR Analytic Server.
• Preview a data query in SAS^® Visual Data Builder.
• Execute a data query in SAS Visual Data Builder.

By default, non-distributed SAS Visual Analytics deployments are limited to running 10 SAS^® Workspace Server sessions simultaneously. If these sessions are all in use, then any other action in SAS Visual Analytics that requires a workspace server session fails. For example, if all 10 SAS LASR Analytic Servers are in use and you attempt to start another SAS LASR Analytic Server or run a query in SAS Visual Data Builder, then the software suspends the action until it can create a new workspace server session. As a result, the software seems to hang.

To increase this session limit, follow these steps:

1. Log on to SAS^® Management Console as an administrative user such as sasadm@saspw.
2. On the Plug-ins tab, expand Application Management ► Configuration Manager ► SAS Application Infrastructure ► Web Infra Platform Services 9.4 ► JobExecutionService.
3. Right-click JobExecutionService and select Properties.
4. Click the Settings tab.
5. In the SASApp Execution Queue Properties section, click the Workspace Server Properties tab.
6. Set the Maximum Threads option to a value higher than 10. You can set this as high as you'd like.
7. Click OK to save your changes and close the dialog box.
8. Restart the SAS^® Web Application Server where the SAS^® Web Infrastructure Platform is deployed. Typically, that is SASServer1_1.
