>Description:
Test mysql 4.0.5 beta installed from binary RPMs:
MySQL-4.0.5-0, MySQL-shared-4.0.5-0, MySQL-devel-4.0.5-0,
MySQL-client-4.0.5-0, MySQL-Max-4.0.5-0
mysqld-max starts normally (including binding TCP socket) and handles
connections via Unix socket normally, but segs when connection made from
another machine via TCP. Quoth the server (my wrap):
/usr/bin/mysqld_safe: line 312: 13509 Segmentation fault \
$NOHUP_NICENESS $ledir/$MYSQLD $defaults --basedir=$MY_BASEDIR_VERSION \
--datadir=$DATADIR $USER_OPTION --pid-file=$pid_file --skip-locking \
>>$err_log 2>&1
with little info in the log (not surprisingly):
/usr/sbin/mysqld-max: ready for connections
Number of processes running now: 1
mysqld-max process hanging, pid 13512 - killed
021203 13:49:00 mysqld restarted
/usr/sbin/mysqld-max: ready for connections
"Non-max" mysqld runs fine so far. Quick ldd doesn't show up any obvious
problems (though I do wonder a bit about the i686 libs, if the binary was
linked against i386 equivalents):
librt.so.1 => /lib/librt.so.1 (0x4002b000)
libdl.so.2 => /lib/libdl.so.2 (0x4003d000)
libpthread.so.0 => /lib/i686/libpthread.so.0 (0x40040000)
libz.so.1 => /usr/lib/libz.so.1 (0x40070000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x4007e000)

libm.so.6 => /lib/i686/libm.so.6 (0x400c0000)
libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
libnss_files.so.2 => /lib/libnss_files.so.2 (0x400e3000)
libnss_dns.so.2 => /lib/libnss_dns.so.2 (0x400ed000)
libresolv.so.2 => /lib/libresolv.so.2 (0x400f1000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
Will work on building from source to see whether error is reproduced.
>How-To-Repeat:
Start mysqld-max. Connect from client.
>Fix:
Don't run mysqld-max.
