I fixed that problem for yum by editing /etc/logrotate.d/yum and changing
"size 30k" to "size 10k".  For CentOS, a 10 kilobyte log file is enough
to hold several months of yum activity, but small enough that the file
will be rotated before a year passes.  You might also explore the
"monthly" or "yearly" options in logrotate.  Right now I don't recall
what I didn't like about using those with the yum logs.
