## To obtain a server thread dump on UNIX

##### Steps

1. Verify that the `server.xml` file for the affected server instance does not include the `-Xrs java-option` flag. Remove the `-Xrs java-option` flag if it exists.

2. If the option is changed, restart the server instance.

3. Use the `ps` command to determine the `java` and/or `appservDAS` processes under which the application server is running.

4. Run the following command on the application server instance:

       kill -3 pid

   The `kill` command redirects the thread dump to the `server.log` file for server the instance.
