As a first pass, just have a look if there are any abnormally large logs. Something like the following will show you which logs are the biggest:
ls -lS /var/log/*log | head
If there are any that are larger than a few megabytes, use tail
to look at the end of them and see if there are any errors that are occurring frequently.
Of course, the disk activity might be caused by something other than writing to logs, so this is just one thing to look at.
