The solution is a bit different from what we discussed on the list before; basically do away with the Medusa request queue altogether and use listen()'s backlog instead.
Last week you were keen that medusa keep processing requests so that it can return a 503 error quickly. I guess your view on that requirement has changed?
This is still something that have to be tested to see what works best. Managing the work with the listen() backlog instead of Medusa's request queue has the benefit of being less resource intensive (Medusa doesn't have to do anything). If Zope is behind a HTTP accelerator/surrogate or load balancer, the surrogate's connect() should fail if the listen queue is full, and it may return 503 anyways (not tested). In the end, the most important point is to put an upper bound on the request backlog (and therefore the response time). Bye, -- Bjorn
