KB440352: Start the Enterprise Manager Service through command line in MicroStrategy on Linux/UNIX causes terminal unresponsive

SYMPTOM
In Strategy 10.x, when start the Enterprise Manager service using the command line of "./mstrctl -s EMService start", the terminal session is left in a unresponsive state.
 
It happens to both bash and ksh shell, with typing feedback not displayed and no reaction to newline. However, the Enterprise Manager service has been brought up in backend.
Below is a snippet of the command output:

-bash-4.1$ mstrctl -s EMService stop
-bash-4.1$ MType=DEFAULT Service shutting down!

-bash-4.1$ mstrctl -s EMService gs|grep state
stopped
-bash-4.1$ mstrctl -s EMService start
-bash-4.1$ -bash-4.1$ -bash-4.1$ -bash-4.1$ -bash-4.1$ -bash-4.1$ -bash-4.1$

Refer to Technical Document below on how to start the Enterprise Manager service using the command line:
KB250929: How to start the Enterprise Manager Service through command line in Strategy 10 on Linux/UNIX
 
REPRODUCTION STEPS
In Strategy Tutorial:

1. Install and set up Enterprise Manager on a Linux machine
2. Connect via command line and change to the /bin directory
3.  Run "./mstrctl -s EMService stop" to successfully stop EM service
4.  Run "./mstrctl -s EMService start" to see the terminal being unresponsive (However, it will successfully start EM service in the back end by checking using "ps -ef |grep EMService" command)
5. Use arrow-up and arrow-down, nothing displays either

 
 
CAUSE
This is a known issue with Strategy 10.x.
 
 
ACTION
This issue has been fixed in Strategy 10.6 GA. Upgrade to the latest feature release version to take advantage of the fix.
 
WORKAROUNDS
There are two workarounds:

• Workaround A:

Type in "reset" and session goes back to normal.

• Workaround B:

Switch to tcsh shell, the service starts successfully.
 
And it is noticed the system throws a string like below:

rehl:/bin>MType=DEFAULT Start EM Service.
