Yes R14A. Which is an unstable beta release of Erlang
(http://www.erlang.org/download_release/7) and should _never_ have been
selected as the version of Erlang for a stable release of Debian. Sigh.

Hmm, I'd expect some growth due to memory fragmentation but not to the
extent you're suggesting. The connections to the server, they're not SSL
connections are they? Also what is the memory in the server, and have
you left the high watermark at its default 0.4?
