as I said , I build mysql41-server from port without any parameters, so you can see libwrap, and i will --without it next time. the smp kernel should be crashed in 2 minutes, so my server is running with UP configuration, and the SMP dmesg wasn't saved. I wonder ADAPTIVE_MUTEXES options is suitable for SMP? I am very likely to see your kernel conf file and mysql build options, they will be very useful, thanks. -- Young Lee On Tue, 29 Mar 2005 10:54:52 +0200 Uzi Klein <uzi@bmby.com> wrote: > Young Lee wrote: > > the system is hang and throw a fatal 12 pannic. > > > > I build mysql41-server from port without any parameters, and the > > thread lib use libpthread.so.1, use ldd to look details as below > > > > admin# ldd /usr/local/libexec/mysqld > > /usr/local/libexec/mysqld: > > libz.so.2 => /lib/libz.so.2 (0x28422000) > > libwrap.so.3 => /usr/lib/libwrap.so.3 (0x28432000) > > libcrypt.so.2 => /lib/libcrypt.so.2 (0x2843a000) > > libstdc++.so.4 => /usr/lib/libstdc++.so.4 (0x28452000) > > libm.so.3 => /lib/libm.so.3 (0x28524000) > > libpthread.so.1 => /usr/lib/libpthread.so.1 (0x2853f000) > > libc.so.5 => /lib/libc.so.5 (0x28563000) > > > > i wonder why should it uses libwrap and libstdc++... > > did you try compiling it optimized? or with linuxthreads? > > > > I use the original SMP kernel configuration file: > > > > admin# cat /usr/src/sys/i386/conf/SMP > > include GENERIC > > ident SMP-GENERIC > > options SMP > > > did you add "options SMP" in your kernel conf? > I can see the kernel loading 1 CPU > > should look like that: > > <snip> > ... > Copyright (c) 1992-2004 The FreeBSD Project. > Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 > The Regents of the University of California.
