>Description:
Recently the server had to be hard-booted... a safe shutdown was not possible.
After the server came back up, mysql
has been acting very funny. When the server first boots, mysql wont respond to
anything. I restart mysql and all works fine
when connecting to Localhost, however when you try to connect to the server via TCP/IP
you get the following error on the
client :
[root@monitor bin]# ./mysqlshow -h www.dis.net -u root -p
Enter password:
./mysqlshow: Lost connection to MySQL server during query
[root@monitor bin]#
At the same you do this on the client machine.. you get this on the host machine :
/usr/local/bin/safe_mysqld: line 269: 26209 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
Number of processes running now: 1
mysqld process hanging, pid 26212 - killed
021015 14:54:14 mysqld restarted
I originally thought it may have something to do with the client.. but even a simple
'telnet www.host.com 3306' will produce
the same error on the server.
I tried starting mysql directly (without using safe_mysqld) by using
/usr/local/libexec/mysqld --user=root. When I did this,
it
didnt spit out an error on the client side, but it does cause a segmentation fault on
the server with no additional warnings
or logs. After that the server fails to respond to anything.
I have re-installed mysql from a secured distribution, so I know it doesnt have
anything to do with any tampering. I have run
checks on all of the databases and they all seem fine. Also, everything works fine
when connecting with a UNIX socket
(Localhost), the problem only appears when connecting with TCP/IP.
