UDPS-510 — The proxy has failed
To prevent consuming system resources, the proxy counts how often a child process terminates. As children in proxies based on UDP do not terminate until the whole proxy is about to terminate, any terminated child signals a potential problem. The proxy immediately starts a new child process. If some serious problem causes process termination over and over again, the proxy would not be able to do its normal work. Instead, it would consume system resources uselessly, especially CPU time and log space. Hence, the proxy terminates if it detects an excessive child process termination rate.
