Comment 13 for bug 1645729

The change has been tested in an affected environment, and shown to stop the memory from growing. As described in Comment #11, the issue is that we were accumulating memory each time an agent acquired a watcher, and never released that memory until the API connection was severed. We now release the memory when the watchers are closed.

There may be additional issues causing agents to repeatedly acquire watchers; there is no change for this as of yet. We have not observed any other problems in the affected environment since the fix was tested.
