problems. Since there is a bit more steam on the system, I get irregular but predictable SSH connection disconnects (ssh client loop send disconnect: Broken pipe). I have already tried all possible combinations of ClientAliveInterval and ServerAlivceInterval (and -CountMax), also TCPKeepAlive. Nothing has changed this situation. Even if I run the Ssh server in the DomUs with -d -d -d (debug level 3), I see no evidence of a cause around the time of the abort.


A `Broken pipe' from ssh means the RHS of the pipeline exited prematurely.
Does dd report anything? media errors? filesystem full? O_DIRECT constraint
violations (offsets and sizes not aligned to block-size because dd(1) is
reading from a (network) pipe--though this is not a problem on UFS)?
