Hi, David. I can't repeat this with just the information you gave me; but I would very much like to find out what is happening. Can you please try a few things for me, to help identify the problem? First, can you turn on the general log? Add this to your my.cnf: [mysqld] log Or start mysqld_safe with the --log option. After the server hangs, check the log file and see what exact commands mysql-front is using. See if you can reproduce the hang without mysql-front (i.e., by using just the 'mysql' command line client, and typing in the exact same commands that mysql-front uses). Can you try using our static binary, instead of the -max binary? If you download our -standard version, you can just move your current mysqld to mysqld.save, and then copy the static binary into place, and restart the server. Can you also please send the output of mysqldump --no-data your-db? If the data are not too large, can you send them as well? You may upload it to ftp.mysql.com:/pub/mysql/upload/bug4979.tar.gz; only MySQL developers have download access to those files. Basically, I am trying to a) get a repeatable test case, and b) see if it might be related to system libraries on RH 9.0, or if it shows up with a statically linked binary as well. Thank you very much for your bug report, and in advance I thank you for any extra information you can provide. Regards, Timothy
