v210 has quite a few bugs in this area. One fairly major one is a
connection leak [1] in the syslog_drain_binder component. When this
happens, changes to the syslog drain bindings do not make their way into
the doppler servers.

I'd strongly recommend you try to move to a newer release.

The system is currently running ~200 apps and they all bind to an external
