But a possible kind of experiment . . . top keeps its ssh connection in use on a rather frequent basis, even if the mount of traffic is not large. Try having some other ssh session into the 12.1 Stable FreeBSD system that also keeps its ssh connection in use on a rather frequent basis. Does it get the same issue as the top sessions do? (Need not be at the same times but if the times were near each other for failures that might indicate something.) Of course, it may be that some of your other ssh connections to the same system already do this test --or it may be they all rarely put their connection to use (compared to top). === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
