Connecting to other than localhost crashes mysqld

Ok, I'm a complete noob to mysql. I've found this section in the docs, but it doesn't address my issue: http://www.mysql.com/doc/en/Gone_away.html
From any computer in my house, I can crash mysqld remotely. Maybe I
have something configured wrong, but I wouldn't think I could have it
configured wrong enough to allow such a simple DoS.
I'm running on:
Linux opal 2.4.18-14 #1 Wed Sep 4 12:13:11 EDT 2002 i686 athlon i386
GNU/Linux
I did the following two test from the local machine mysqld is running
on: ("xxx" is not my password, but that is what I really typed)
[root@opal root]# mysql -u root -h localhost -pxxx
ERROR 1045: Access denied for user: 'root@localhost' (Using password:
YES)
[root@opal root]# mysql -u root -h `hostname` -pxxx
ERROR 2013: Lost connection to MySQL server during query
The first one was as expected "Access denied", but the second one
caused it to crash. Same thing happens when trying to connect from
other machines in my house.
When it says "Lost connection..." it logs the following:
Number of processes running now: 1
mysqld process hanging, pid 31458 - killed
021007 02:24:14 mysqld restarted
/usr/libexec/mysqld: ready for connections
Here's my version info:
[root@opal root]# mysqladmin version -p
Enter password:
mysqladmin Ver 8.23 Distrib 3.23.52, for pc-linux-gnu on i686

So did I overlook something really obvious or is this a known problem?
