It's pretty new functionality and there is not yet a good example plugin that uses it (it makes most sense for database plugins, where I have limited knowledge). It would be useful to read this first (unfortunately not an easy read: http://download.rsyslog.com/design.pdf Actually implementing it is rather easy. The core point is that for system-induced errors (those that can be retried) the plugin must return RS_RET_SUSPENDED and for message-induced errors it must return an "real" error state (like RS_RET_ERR, but it would be better, and I'd be glad to include, more precise error codes). The core engine than knows what to do. Well, the core may have undiscovered bugs right now, as this functionality was never before used in practice. It is very criticial to think about which error class a failure belongs to. Messages with message-induced errors are simply thrown away, so one needs to think twice before assigning this class - but on the contrary if such a message is flagged as system-induced, it will block the system, just as you can currently see...
