No, it hasn't!  30MB is the default journal size for a sufficiently
large filesystem, and the journal file *never* grows.  It can't ---
the ext3 code simply does no regular file IO to the journal, ever, so 
there's no opportunity for the journal file metadata to change in any
way whatsoever.  All journal file IO is done "under the hood" as it
were, submitted directly to the block IO layer.

Not due to ext3.  There are many possible reasons for the root fs
filling, such as installing multiple bootable kernels (fills up
/lib/modules), log file growth, large files in /tmp and so on.  The
journal never grows.
