Site Database errors

I get strange errors like the following on most pages:

user warning: Table './strobede_catch22/accesslog' is marked as crashed and should be repaired query: INSERT INTO accesslog (title, path, url, hostname, uid, sid, timer, timestamp) values('Memory Management for Large-File Editors (Part 2)', 'node/68', 'http://www.catch22.net/tuts', '118.209.3.231', 252, 'a56f91f5e8d5859bd6f9ec69ad2922ff', 439, 1260951351) in /home/strobede/catch22/modules/statistics/statistics.module on line 64.
