This is a bit vague description of the problem. Have you
done anything 
to diagnose why the lamd would not respond anymore ? For
example, have 
you tried attaching to the "hung" lamd with gdb or
using 'strace -p' 
to know what the process is actually doing ?

No. Especially with kernels from an enterprise class Linux 
distribution which should not change too much between
updates.
