Goldstein Lyor commented on SSHD-346:
-------------------------------------
This may be a problem if the _hostkey.ser_ file is somehow deleted when the
server is re-started. In such cases, the server will generate a *new* set of
keys, which will have a different fingerprint - in which case (most) clients
will reject it (at least when running in batch mode)
> "key_verify failed for server_host_key" Error

> Hi.
> We implemented the server using 'Apache MINA SSHD'.
> Function has been completed, we are testing performance.
> We call each 1000 'scp' command through a number command window.
> Then, the following error occurs intermittently.
> -----------------------------------------------------------
> key_verify failed for server_host_key
> lost connection
> -----------------------------------------------------------
> This occurs on both v0.11.0 and v0.12.0.
> And v0.12.0 is occured more frequently.
> Gerrit also have the same problem, but i know that it fixed in a particular
> version.
> I'd appreciate it and tell you how to solve.
> Thank you
