clustermon (because of modcluster) also affected... +++ This bug was initially created as a clone of Bug #1076711 +++ Just observed a situation where the current polling code breaks in case of input being the exact multiple of the read buffer size (4096). The cardinal issue is that the code didn't expect POLLHUP to appear when not original asked for capture, and in turn, not expecting poll will return positive number in such case, leading to fallback to "nothing read of malformatted input" condition. This is partly in one line with previously discovered issues ([bug 732483]), which led me to some more code base reviews, resulting even in a patch to this very issue (although it was more like fix "suspicious" than "apparent" back then): [1]. Unfortunately there was no direct justification for that patch at that time. [1] https://git.fedorahosted.org/cgit/conga.git/commit/?id=631b17aab8f44396c4cf373bc4466bbfcaab6563
