Nope, doesn't help ... I've been doing this for years now, and its all scripted, to make sure that I don't make a mistake like that ... its a reproducible issue with 4.x and the EM drivers ... or, rather, the 4-STABLE ones ... in fact, I have three servers with em devices, one of them I *haven't* upgraded to the latest, since I knew if I did, the problem itself would creep onto that machine ... the other two are running reasonably "new" (for 4.x, of course) -STABLE kernels, and both exhibit the problem ... I'm not overly concerned, it just takes 30-60 minutes for everything to usually time out and become visible on the 'Net again ... and, starting in April, we're going to be upgrading our servers to 6.x ... just figured I'd make sure there wasn't some command I was overlooking that I could give it a kick with, until then ... Thx though ...
