analyse core file using pmap and pstack

Dear All,
I am new to this forum. This is my first.
I am facing customer issue. Customer has got core file while running the server.
He had sent core file and details from pstack, pmap and pldd commands.
I have to debug this application, please help me to fix this issue.

I am using sparc 10 solaris machine. Code is not given.

Any help is appreciated.

Thanks
Kiran
