In our server Check pointer process is consuming 8 GB of memory, what could
be the possible reason? Can any one please help.

Are you sure you're measuring the memory correctly? The RES field in top output, for example, includes shared memory, ie. the whole buffer cache. Shared memory isn't really "consumed" by the checkpointer process, but shared by all postgres processes.
