Currently I are using Jenkins ver. 1.4.39. I have Jenkins SSH plugin installed.

Working Scenario: Connected to SSH Slave as user X and performing build promotion.
I am using 'Send build artifacts over SSH' action to copy the required files to the SSH Slave to a folder owned by user X. I provided the required shell commands in Exec command. I am able to successfully complete the promotion.

Failing Scenario: Connected to SSH Slave as user Y and changing user to X and performing build promotion.
I am using 'Send build artifacts over SSH' action to copy the required files to the SSH Slave to a folder owned by user Y. I provided the required shell commands in Exec command. I want to sudo as user X for which I gave command 'sudo su - X'. When I promote the build I am receiving below error message.
ERROR: Exception when publishing, exception message [Exec timed out or was interrupted after 10,004 ms].

sudo command is not working for me through Jenkins even though I checked Exec in pty option required for running sudo commands. I am able to run the same command on the linux machine successfully. I set the option to Password not required for user Y to change to user X.

Please help me by providing a fix. I really appreciate your assistance.
