Martin, Larry, > Synopsis: Server crashes on remote connection
I'm not a Unix guru but I experienced the same sympton on SuSE Linux 8.0/8.1, and I heard of people reporting the same of Red Hat Linux 7.x/8.x. MySQL runs stable, you can connect from localhost via socket and tcp/ip, but as soon as you try a connect from some other machine, mysqld segfaults. In all cases I heard of, the problem was some glibc version that caused all the trouble. You say you use > glibc-2.2.93-5 This version # looks a bit strange to me, well ... In a SuSE Linux Newsgroup I heard that everything's okay if you use >= 2.2.5-151. We use glibc-2.2.5-164 on SuSE Linux 8.1, and with our 3.23.54, we've had no problems at all.
