[CentOS] Network hangs after several hours (Centos 6 recently upgraded kernel/glibc)

Just noticed that in the trace, it shows an old kernel, so I don't think
grub was automatically selecting the latest kernel. Just wondering what
process updates the default to be the latest kernel, and if a problem could
be an update but grub selecting an older kernel, but other packages updated
?
