On a system is used to provide ftp services using RHAT 7.3, I've recently gotten
kernel messages that don't look healthy and seem to indicate that there is
problem with vsftp itself. I keep both boxes at current errata levels.

[root@zenIIIa root]# rpm -q kernel glibc vsftpd
kernel-2.4.18-19.7.x
glibc-2.2.5-42
vsftpd-1.0.1-5
