On last 2 days, sometimes my APC misses rate is almost 100%, with "hits" only 1, and "misses" more than 1000 (i can't remember the exact "misses" value, but the "hits" is only 1 for sure).
When i restarted the httpd, everything went fine again.
Here are some lines from stderr.log, any useful information there?
And there is 1 unique line there
Additional information:
I just found that someone scanned my server with malicious purpose and he/she generates lot of 404 error on my error log.
Maybe the 404 not found causes lot of misses? (because the file does not exist so APC can't cache it?)
