why error_log was written many times for same item?

[Jen mlists]

Hello,

In my mp1 script I wrote some info to apache's error_log:

    } elsif ($ip_int != $ip_int2) {
        $r->log_error("[$ip FORBIDDEN] Request IP was not matched");
        return FORBIDDEN;


But I saw it wrote many times for same error item,like:

[Tue Aug  7 16:24:08 2007] [error] [219.129.83.13 FORBIDDEN] Request
IP was not matched
[Tue Aug  7 16:24:08 2007] [error] [219.129.83.13 FORBIDDEN] Request
IP was not matched
[Tue Aug  7 16:24:08 2007] [error] [219.129.83.13 FORBIDDEN] Request
IP was not matched
[Tue Aug  7 16:24:08 2007] [error] [219.129.83.13 FORBIDDEN] Request
IP was not matched
[Tue Aug  7 16:24:08 2007] [error] [219.129.83.13 FORBIDDEN] Request
IP was not matched
[Tue Aug  7 16:24:08 2007] [error] [219.129.83.13 FORBIDDEN] Request
IP was not matched
[Tue Aug  7 16:24:08 2007] [error] [219.129.83.13 FORBIDDEN] Request
IP was not matched
[Tue Aug  7 16:24:08 2007] [error] [219.129.83.13 FORBIDDEN] Request
IP was not matched

Why this happen?Thank you.
