I have been seeing a recurring issue on my web server:
[Sun May 16 03:10:19 2010] [crit] (28)No space left on device: mod_rewrite: could not create rewrite_log_lock
Configuration Failed
[Sun May 16 04:10:05 2010] [crit] (28)No space left on device: mod_rewrite: could not create rewrite_log_lock
Configuration Failed

[Sun May 16 05:17:13 2010] [crit] (28)No space left on device: mod_rewrite: could not create rewrite_log_lock
Configuration Failed
So far, the only fix I have found to this when it happens is to reboot my server. This is non-ideal :-\
Restarting httpd does not clear the error. df indicates I have 20+ gigs free, and top and free both  report 800+ megs (or 1.2 gigs)

Any ideas on why this would recur, and how to prevent/fix it?
