Repeated fatal error on kloxomr7 -incomplete headers (0 bytes) received

[qtriangle]

Kloxo mr is a brilliant software. I use it on many of my servers.
Mostly I have version 6.
However, now I have started using version 7 because it has so many excellent features like free SSL.

On kloxo mr 7, This error is received whenever a new client is added [when trying to access first added domain]:
 
 [error] [client x.x.x.x] FastCGI: incomplete headers (0 bytes) received from server

I have 2 servers, it happens on both.
One was upgraded from kloxo-mr 6 and the other is fresh install of kloxo-mr 7.
Both are on Centos6, 64 bit.

The error goes when following 2 commands are run:

• fixweb-all
  restart-all

However, alarming thing is that this happens for every new account, without fail.
I think this is due to some php-fpm issue. However, no clue what causes this.

If you see more this error, maybe your server try to DDOS by someone.

[qtriangle]

This problem comes only when we add a domain to a new account.
For other old domains, everything works fine.
After running the scripts, it start working for new domains too.
That doesn't look like DDOS, because it becomes fine after running the scripts?

Try change to 'dynamic' for 'php-fpm type' under 'web features'.
