Finally got a test environment set up. Unfortunately, we don't seem to be able to reproduce the 
problem on the test servers - they work perfectly.. so we swapped out one of the test servers for a 
production one, and the production one is still exhibiting the leak.

It appears that the leak just occurs over time - seems to be unaffected regardless of whether 
ldirectord is routing traffic or not.. the software set up is the same, which makes us wonder if 
maybe some sort of hardware issue at play...

Anyway, below are links to a debug log of 1) the production server which is showing the leak, and 2) 
a test server (set up the same) which is not. Personally I can't see much that's different, but a 
more trained eye might spot something.
