Ia have one CentOS 6.4 64 bit with  JRE version 7u40. 

I installed this bin file : http://www.manageengine.com/products/service-desk/91677414/ManageEngine_ServiceDesk_Plus_64bit.bin

Everything OK at first startup usin run.sh but after a restart the run.sh returns the following message:

" Unclean shutdown of previous run.   Failed to start the server "

How can i start ServiceDesk Plus again?
