We are running IEM 8.2.1409.0 in a Windows environment, and we are currently having a problem with some of our relays where the forwardingbufferdir is filling up with the maximum number of files. We can copy the files to the server bufferdir and they get processed. So, we know the files are not bad. For some reason, once the forwardingbufferdir fills up, it stops reporting and all clients reporting to it stop reporting. Simply, restarting the relay service and client service does not resolve the problem. The files in the forwardingbufferdir have to the deleted and the services stopped and started.
