These messages are internal to valgrind, but they have some utility for users.
They indicate that valgrind's memory manager was asked to handle a block 
(actually
a single contiguous address interval, which could be a block or a non-block)
of more than 100,000,000 bytes.  Such a large interval is unusual and might
indicate an error, especially on a system with 32-bit addresses.  But on
x86_64 with 64-bit addresses and much more latitude for placemement of PT_LOAD,
this might be OK.  Where are your PT_LOAD?  [readelf --segments <executable>]

When I was working in this area of valgrind, then I improved the message
to include the actual address values as well as the length.  Often this
made it easy to determine whether to be concerned.
