This has come up before under a slightly different discussion. My prime feedsite accidentally added shitloads of groups with illegal characters in them ( @ ; < >, etc. ) These have been manually flushed, but nntpcached insists these groups still exist, which is causing many programs to GPF or coredump when they try to parse the active and newsgroups lists. A restart did _not_ remove them, nor did a SIGUSR1. I now have several hundred pissed off readers and the problem needs fixing fast, preferably without having to resort to blowing away the spool and starting over. Anyone got ideas on how to remove 'em? AB
