Ok, I've disabled SSL Authentication on the Collector and, although it's early days, it would appear that the memory usage is stable.
If that remains the case, is there anything we can do to help you track down the leak in the SSL code?

I was just thinking something like
condor_status -const 'Name == slot1@xxxxxxxxxxxxxxxx' -l | wc --bytes
but for ~1000 ads, even at ~2500 lines each, we're just not talking all
that much storage being required.

We've had problems with memory leaks in our SSL code, but we're
not currently aware of any. It would be interesting to know what happens,
if it's easy for you to temporarily switch back to just pool password.
