no room in free client client list

[Vincent B. <vin...@ma...>]

Hello,

I am working on a project to replace our current squid infrastructure by a brand new bluecoat platform.

For this I developed a little script to automatically generate some curl-loader configuration file.

this is running pretty well, generating some thousands of urls simulating thousands of users surfing on the net but I get a little error message that continuously comes back.

		put_free_client - error: no room in free client client list.
		mperform_hyper error: cannot free a client.

I do not know what it is exactly and how I can solve it ?
