I have a setup for transparent caching with my SP client and as of now we are using leastconn as predictor with A2(1.3) as the version.
here are my pain points:
1. The Cache guys tell me the moment we turn normalization ON the caches cant FTP the logs to their FTP servers (the traffic/conn drops after sometime).we dont have randomization ON.
I feel its more of the cache issue or of the connection than of security as normalization will either allow or disallow but will not terminate after some time.
2. also im observing in "show stats" output , lot of "Total layer4 rejections" and some Layer7 conns, and "Total times rserver was unavailable" .. as we see probe-fails a lot when traffic peaks up thus making cache to be out-of-service , need to know when do we have these issues.does it need to have the whole farm to fail or is it for connections failing for a single cache-server?
any good links to find more on the troubleshooting aspect of ACE ?
