I have had trouble over the past few days with innduct generating unreasonable amounts of debug log. Mostly, the messages look like this: Oct 18 08:40:01 chiark innduct[3270]: nntp.[elided]| debug: filemon inotify: read event with unknown wd=5447913 Oct 18 08:40:01 chiark innduct[3270]: nntp.[elided]| debug: filemon inotify: startfile 0x55de6bf4e6b0 wd=5447914 pf=0x55de6c096840 Oct 18 08:40:01 chiark innduct[3270]: nntp.[elided]| debug: filemon inotify: stopfile 0x55de6bf4e6b0 wd=5447914 pf=0x55de6c096840 Oct 18 08:40:01 chiark innduct[3270]: nntp.[elided]| debug: filemon inotify: read event with unknown wd=5447914 Oct 18 08:40:01 chiark innduct[3270]: nntp.[elided]| debug: filemon inotify: startfile 0x55de6bf4e6b0 wd=5447915 pf=0x55de6bfbfd10 Oct 18 08:40:01 chiark innduct[3270]: nntp.[elided]| debug: filemon inotify: stopfile 0x55de6bf4e6b0 wd=5447915 pf=0x55de6bfbfd10 Oct 18 08:40:01 chiark innduct[3270]: nntp.[elided]| debug: filemon inotify: startfile 0x55de6bf4e6b0 wd=5447916 pf=0x55de6bff38d0 This seems to have been triggered by the peer being in "expiring" state for several days and responding to every article with 431. I think I have diagnosed the problem. If my fix holds up, I will upload it.
