On occasion, openPDC manager will fail to start, with the following exception. In testing, this has occurred about one in fifteen times, on a fresh install.
 
Ritchie mentioned that "the likely solution is to wrap connectsync function call in a try/catch and ignore both object diposed and null exceptions since these can occur when a thread is trying to process a queued socket request for a socket that is already closed."
