Hello fellow listers! I've got some errors starting to crop up on one of my CentOS5 boxes. Below is a transcript:

 =======================

There are others with various app names besides vi including httpd, named, sftp-server, etc..  Is this an imminent hardware failure? Do I have kernel issues? I've checked the system with lm_sensors and temps are perfectly normal. Also, performance and operation seems to be fine. Even with these errors, my services are running without any hiccups. HELP! :-)
