Hi All,

I've got a situation where I'm using t.w.c.Agent to make 100,000 POST request against a server. Each time a new Agent instance is built and the request is sent using it. After about 20,000 requests, I get this error:

Failure: twisted.internet.error.ConnectError: An error occurred while connecting: 99: Cannot assign requested address.

Would building the Agent once and reusing the same instance avoid this? I assume I've run out of client ports.

Yes... except it doesn't support persistent connections yet. Do you actually need to run all 100,000 in parallel? If not, set a cap on how many requests can run in parallel.
