in thread Net::OpenSSH loosing lines ins reply
The ssh command that is being run under the hood by capture is leaving STDOUT in non-blocking mode. The issue seems fixed in newer versions of OpenSSH, or at least I am unable to reproduce it with the latest one (6.6.1p1).
In any case it is easy to workaround. Just using capture2 instead of capture or setting stderr_discard => 1 should make it go.
BTW, there isn't any difference on the fdinfo dumps between the successfully and failed invocations because the problem is hidden behind a race condition. The perl process needs to be faster writing than tee reading for the intermediate pipe buffer to fill.
