Hi Abdul, Seeing you mention "Error""tomcat-ajp-nnn" etc perhaps there will be some informative details in the tomcat connector log. Now you don't specify OS or WEB details but I guess Unix (/mnt) of some sort and perhaps Apache. So check the connector log eg cf10/config/wsconfig/n/mod_jk.log for [error] or [warning] messages.
Let me know if that turns up anything or not helpful and need more idea's. Carl.
