A couple of months ago we moved from 11.3-RELENG to 12.1-RELENG (server side,= clients were always 13-CURRENT or 12-STABLE). With FreeBSD 11 as the backend, those brok= en pipes occured, but not that frequent and rapid as it is the fact now.=20 The "problem" can be mitigated somehow: running top or using the console pr= events the broken pipe fault for a while, but it still occurs. Running "screen" (port sysutils/screen) does extend the usability of the console for a significant= timespan, but the broken pipe also occurs randomly, but it takes a significant time to oc= cur. All systems mentioned above are highly customized, so I used the chance of = another, more "generic" scenario to test. The backend is a most recent Xigmanas machine (= running Hardened FreeBSD 12, latest official issue, its based on FBSD 12.1). Access= ing clients are recent GhostBSD or FreeBSD 12.2-RELENG, utilizing Remmina (port sysutil= s/remmina). It doesn't matter whether I take the ports from our local poudriere driven rep= ository or from one of the official ones. SSH via Remmina dies the same death as it do= es on all customized boxes. And those failing scenarios are occur in all kind of netw= orks, home-ISP-lab/work, lab's network, home's network with foreign, Linux based = CPE or other vendor's CPE. My conclusion is: either there is a serious problem with FreeBSD since 12, = or there is a config issue I'm not aware of, even with "vanilla" installations from offic= ial repository running unchanged.
