+      The log files generated by BOINC's daemons and servers can grow to gigabyte size in a few days or weeks, and will eventually fill up your disk. When this happens your project will grind to a halt. In addition, if you use db_dump to export statistics, directories with names of the form '''html/stats_2006_4_3_15_50_2''' will build up, and you'll need to delete and possibly archive them. Most projects do this manually.
+
+Initially you can deal with log files by hand, but eventually you may want an automated solution. Log rotation typically must be done while the project is [http://boinc.berkeley.edu/tool_start.php stopped].
+
+(Note: Eric Myers wrote a detailed page about log rotation, which is [http://www.spy-hill.net/~myers/help/boinc/log_rotation.html here]).
+
+Here's a shell script (from Nicolas Alvarez) that tars and compresses log files (you'll still need to eventually deal with the compressed files). You can run this script as a periodic task in [http://boinc.berkeley.edu/configuration.php config.xml].
