Given what Konstantin Belousov described (default stack space sizes and apparently guard pages eat into stack space instead of the overall space being bigger by the guard size), I think that would explain not moving from CURRENT: it was known to be a problem. (Although I expect Konstantin Belousov's note here is the first public description of the problem's details.) I agree that you did not get an answer for the other part: > I simply asked if it's safe to assume the sysctl to be an integer in > 11.1 I've not gone through any draft 11.1-release code to check. === Mark Millard markmi at dsl-only.net
