Gateway Service Does not Start and Tableau Server is Degraded

Issue

Gateway Service does not start and Tableau Server is degraded.
"tsm status -v" output includes the following:

Status: DEGRADED
'Tableau Server Gateway 0' is in an error state.

Check the startup.log in httpd for the following (pid number will be different):

httpd (pid <number>) already running

Although the gateway is isn't running, there is an existing httpd.pid in one of the following locations.

Linux: Look for a file httpd.pid in /var/opt/tableau/tableau_server/data/tabsvc/logs/httpd/
Windows: Look for a file httpd.pid in C:\ProgramData\Tableau\Tableau Server\data\tabsvc\logs\httpd

Environment

Tableau Server

Resolution

Stop the server using tsm stop
Linux: Locate httpd.pid in /var/opt/tableau/tableau_server/data/tabsvc/logs/httpd/
Windows: Locate httpd.pid in C:\ProgramData\Tableau\Tableau Server\data\tabsvc\logs\httpd
Manually remove the httpd.pid file.
Run tsm start to start Tableau Server and use "tsm status -v -u <username>" to confirm gateway service is up and running.

Cause

Due to unexpected Tableau Server downtime, the httpd.pid file, which is generally removed on shutdown, was not removed.
