I'm using embperl 1.3b5.
The machine is a dual Pentium III 600 with 1Gb of ram, and a 100Gb disk
array.
Another strange thing is this:
$ tail -500 access_log |grep 500
xxx.xxx.xxx.xxx - - [03/Oct/2000:12:06:27 -0300] "GET / HTTP/1.0" 500 536
"-" "Mozilla/4.0 (compatible; MSIE 4.01; Windows NT)"
xxx.xxx.xxx.xxx - - [03/Oct/2000:12:07:38 -0300] "GET / HTTP/1.0" 500 536
"-" "Mozilla/4.0 (compatible; MSIE 4.01; Windows NT)"
and in the error_log:
$ tail error_log
[Tue Oct 3 11:19:16 2000] [error] [client xxx.xxx.xxx.xxx] File does not
exist: setup.exe
[Tue Oct 3 11:19:22 2000] [error] [client xxx.xxx.xxx.xxx] File does not

[8062]ERR: 30: Line 1: Not found www.babylon.com
[8062]ERR: 30: Line 1: Not found www.babylon.com
As you can see there is nothing in the error log related to the
internal server error entry in the access_log.
If anyone have an idea of what is happening I'd appreciate any help.
Thanks.

Re: Segmentation faults
Posted by Daniel Grunblatt <da...@infonegocio.com.ar>.
We always had that, but I guess I solved it, it was the
MaxRequestsPerChild directive on apache's httpd.conf , I set it to 10 and
the problem was gone, may be it was because the childs grown up too much,
up to 26M, now the max grow up size is 7M.
Thanks anyway.
