For a week or so, I have high load (2.5-3.0 and higher) by some Apache2 processes.
top:
Code:

Top also says, that problem is in apache 2 processes:
Code:
25118 www-data 20 0 57804 30m 5344 S 62 0.9 0:06.02 apache2
24741 www-data 20 0 65432 35m 5888 R 17 1.1 0:16.92 apache2
Now, lsof -p 25118 says:
Code:

Note: different_site is actualy real website.
As far as I can see, reason for load is apache2 writing custom error logs.
Now, I need your suggestion, how to fix this?
Disable apache2 error logging? Or am I interpreting readings totaly wrong?
I'm running Etch with ISPC3.
Any comment, advice is appritiated.
