Apache error 103

V

vamos

Hello, I have a problem with my Apache webserver, I've made some configuration to block DoS requests, but someone has found how to panic my Apache, when I run [cmd=]netstat -nb | grep SYN[/cmd]
I find 1-2 IPs every minute who send little requests
Code: 
web# netstat -nb | grep SYN
tcp4       0      0 *.*.*.*.443      82.227.190.9.49809     SYN_RCVD
tcp4       0      0 *.*.*.*.80       83.195.93.238.63327    SYN_RCVD

The Apache server crashes and:
Code: 
Erreur 103 (net::ERR_CONNECTION_ABORTED) : Erreur inconnue
I need to block the IP and restart Apache, but they come back every time with another IP.

Does someone know how to make stable Apache or have another idea?

Thanks in advance :(
 
FreeBSD 8.2 is end-of-life, update to at least 8.3. And what version of Apache 2.2.x?

It's possible the crashes are caused by bugs in Apache. Knowing what the exact version is would help searching for those bugs.
 
Hello, it's not an apache problem, the problem is only when there is these strange attack

Server version: Apache/2.2.23 (FreeBSD)
Server built: Feb 10 2013 02:54:09

I will change of FreeBSD soon but I want to resolve it before
 
There are some reports on the net about Apache 2.x issuing errors 103, for example an issue which is related to mod_cache/mod_mem_cache:

https://issues.apache.org/bugzilla/show_bug.cgi?id=50024

I cannot tell whether this one is related. Anyway, disabling some non-standard plugins would get you a jump-start to trouble shooting.

If you could identify certain repetitive characteristics of the packets bugging your server, then perhaps you could block them using a firewall.
 
Hello, a friend have tell me to put nginx or lighttpd as proxy server with apache, but that will be a solution ? if yes how ? thanks.
