So the error means that poll() is being passed an nfds argument too large, larger than the process could have open as fds. It looks like the code, for some reason I cannot understand, passes poll() a pollfd structure for each child process...with fd=-1, so that it will be ignored. Uh, why? Why is it passing pollfd structures to the kernel that it *wants* the kernel to ignore? It seems that the code could simply skip over allocating and filling in those pollfd structures and have the exact same effect. As for what changed, well, something changed the number of child processes you're experiencing (load?), or the process fd limit (RLIMIT_NOFILE) for dansguardian changed. Philip Guenther
