Subject: [BlueOnyx:13059] Possible attack - Limited resources

 

Hi,

 

i'm having trouble with my BO server.

 

Few minutes ago one of my customer contact me saying that his website was
down.

 

I've connected to server through SSH and i was unable to restart httpd.

 

There were 3 httpd processes "froze"

 

So i'v done kill -9 PID and restarted httpd

 

All works fine.

 

 

The problem is that if I restart httpd all the memory (RAM) will be
completely used.

 

running top from terminal says that there are a lot op httpd processes,
responsible of that big RAM usage.

 

Is there any kind of DoS attack?

 

What can i do?

 

Thanks

 

Marcello
