The semaphore timeout period has expired

I've a couple of services running on the same virtual using metrics.net, and occasionally 1 of them starts throwing this error. I think it may be caused by network hiccups. It doesn't recover from it automatically, so I have to restart the service to fix it (possibly because HttpListener is re-initialised?).
