Too many connections to the server

Hi there,
I have ran into a problem now.

I am trying to "refresh Info" on my sites.
Several of the sites are located on the same server, and I therefore run into problems.

After failing to "refresh info" I contaced my hosting company, and I got the following feedback:

The IP address is being blocked repeatedly by our server firewall for having too many connections to the server. I've unblocked it now, but it instantly became blocked again due to having 187 open connections to the server. You'll need to limit the number of connections the script is making to the server simultaneously, or the IP will always end up being blocked.

How can I limit the amount of simultaneous connections?

hmmm, strange.
I only got 7 sites on that server that keep blocking me, and it has all been fine up until now.

I do however also have another sw component (SP Staging) that is refreshing the info from the sites.

I will check with my hosting company to verify what component the requests are coming from.
