Hmm, I'm not sure how Slony comes by that number, so this might or might
not be meaningful. I agree with the other respondents that the symptom
sounds exactly like broken renegotiation --- the earliest security
patches to close the openssl CVE hole resulted in failures exactly like
this whenever the server tried to force key renegotiation. You might
check whether libssl was recently updated on either the server or client
machine.
