There was a GC bug in 17.5 mentioned at http://erlang.org/pipermail/erlang-questions/2015-June/085032.html as OTP-12821 .  You may not be running into that though.  I have seen abnormal GC memory growth with the 17.5 release (from the download page) but not the 18.0 release, and am not sure about the exact changes it was related to (only that it caused the Erlang VM to be killed by the Linux OS, if you are interested in the testing, it is at https://groups.google.com/forum/#!topic/cloudi-questions/bw2D7YOFtKU).
