CAS writes log files to the
directory. If desired, you can
reconfigure CAS to write log files to another location.
<install
path>
\CAS\workspace\logs
CAS rolls a log file once it exceeds 100MB, and the CAS Service keeps 10 backups of its log.
Note
If you delete the log file, the CAS Service recreates the log only when you restart the service. So it is possible to delete the log, run a crawl, and not have logging information if you did not restart the service.
