./amsmgr: line 101: cd: admin: No such file or directory

This question also has to do with AMS on EC2 (ami-766cce1f)

I located some (apparently) helpful docs at http://help.adobe.com/en_US/flashmediaserver/amazonec2/flashmediaserver_4.5_amazonec2.pdf. This document refers to FMS 4.5, not AMS 5, but I haven't been able to find any docs referring specifally to AMS 5.

Where the document refers to the fmsmgr command, I'm using amsmgr. I followed the instructions on page 26 of the doc, and edited conf/ams.ini to contain:

SERVER.ADMIN_USERNAME = admin

SERVER.ADMIN_PASSWORD = mypassword

SERVER.ADMINSERVER_HOSTPORT = :1111

I then run:

./amsmgr server ams restart

with no problems and get no errors.

When I run

./amsmgr adminserver restart

I get:

[root@ip-10-140-6-120 ams]# ./amsmgr adminserver restart

Admin server:amsadmin command:restart

./amsmgr: line 101: cd: admin: No such file or directory

Stopping Adobe Media Admin Server (please check /var/log/messages)

Admin Server has shutdown...

Starting Adobe Media Admin Server (please check /var/log/messages)

That message about 101 concerns me. I get it if I rerun the adminserver restart command as well.

What is this message telling me, and what do I need to do to fix it?
