openssh unix dev - Feb 2007 - unexpected error message ( ...[auth.error] error: channel 0: chan_read_failed for istate 3)

Hi,

when scp'ing a file from hostA to hostB I receive following error message on
the server side.
Message in authlog:
Jan  9 15:01:32 zapphod sshd[3229]: [ID 800047 auth.error] error: channel 0:
chan_read_failed for istate 3

The file itself is transfered correctly, so I'm wondering why this error is
being logged and what this error message means

It seems that the occurance of this message is not platform specific, as I
have tested it on following systems
platform: SuSE SLES 9, Solaris 8 & 9
SSH version: OpenSSH 4.5p1 + OpenSSL 0.98d

does anybody have an idea, what's the reason for this error message ?

thanks

Jochen
