Hi Christian, You're probably hitting the workspace_client (or workspace_backend) limit. Those are varnishd parameters [1] that default to 64k. I've not checked the regsub implementation, but I guess it is not able to allocate enough memory in the workspace and in that case it simply returns the original input string (the alternative would be returning NULL or killing the child process in an assertion). Try to increase those parameters and try your test again.
