Re: [libssh2] Hanging in libssh2_channel_free?

So it finally stopped - and I can see what it supposedly died on:

Any ideas?

Subject: Hanging in libssh2_channel_free?

Hello,

I'm using the 0508 libssh2 snapshot with curl's snapshot from 0507. And
from all that I can tell, libssh2 goes into a black hole when it tries
to finish up the SFTP connection.

I can see the file moved across, all the data is present, but the
libssh2 debug output looks like this - and then it just hangs. Curl is
waiting for it to return from the libssh2_sftp_close() call.

So my file is transferred, but the sftp_close() hasn't returned so my
program can't continue on.

I can't imagine that no one has tried to upload with libssh2 over SFTP
with curl, but maybe that is the case. I'm hoping it is a configuration
step I'm missing.

Any ideas?

Thanks so much,

Cary FitzHugh
