It looks like a "heap" to me. Some library is allocating a lot of virtual memory. It could be via Postfix, or via an NSS module, perhaps "db" entries in nsswitch.conf, just to close out the Berkeley DB theme. Otherwise, run a test Postfix instance with a default configuration, and add one feature at a time, until the memory footprint jumps... -- Viktor.
