Hi,
I was trying to fix "ES 1.2.0 Pack randomly hangs on server start up".[01]
While tying to fix above issue, I compared debug logs and observed that
server caused to hang-up when
"org.wso2.carbon.tomcat.ext.servlet.DelegationServlet" is not activated.
Compared debug logs are as bellow.

Above issue is observed in Carbon 4.3.0.
According to the observations, this severer hang-up is caused when
*org.wso2.carbon.tomcat.ext.servlet.DelegationServlet.init()
*is not executed. (i.e org.wso2.carbon.tomcat.ext is not active)
