mremap during strace

When I run an strace on an http user pid, I'm seeing hundreds if not thousands of these type of messages..

mremap(0xb70ca000, 606208, 606208, MREMAP_MAYMOVE) = 0xb70ca000
mremap(0xb70ca000, 606208, 606208, MREMAP_MAYMOVE) = 0xb70ca000
mremap(0xb70ca000, 606208, 606208, MREMAP_MAYMOVE) = 0xb70ca000
mremap(0xb70ca000, 606208, 606208, MREMAP_MAYMOVE) = 0xb70ca000
mremap(0xb70ca000, 606208, 606208, MREMAP_MAYMOVE) = 0xb70ca000
mremap(0xb70ca000, 606208, 606208, MREMAP_MAYMOVE) = 0xb70ca000

They're all in a row... I don't know if this is normal or what, but too much of any type of message is usually bad mremap during strace just wondering if anyone could let me know why it would be doing this.... a verification that this is bad and / or a solution or something to check would be wonderful.

Thanks!!
