[stunnel-users] "SSL_read returned WANT_READ: retrying" at 30Hz

Hi,

I'm trying to use rsync (2.6.8) through STunnel (4.16) to synchronize two PC over the internet (they both have the same version of stunnel and rsync).

On the server, I have STunnel running with this configuration: cert = stunnel.pem

; Some performance tunings socket = l:TCP_NODELAY=0 socket = r:TCP_NODELAY=0

; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log

[rsync] accept = 273 connect = 873

On the client I have this configuration: cert = stunnel.pem

; Some performance tunings socket = l:TCP_NODELAY=0 socket = r:TCP_NODELAY=0

; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log

client = yes

[rsync] accept = 873 connect = UrlOfMyServer:273

Then I connect with rsync using rsync -a -h --progress --stats --partial Account@localhost::RemotePath LocalPath

I think the connection is not really stable. RSync sometimes hang. The log file on the client side show 2006.09.11 21:33:11 LOG7[2008:1468]: SSL_read returned WANT_READ: retrying at 30Hz (that's right, it means 30 times a second). My log file nearly gets bigger faster than my downloaded file ;)

Is it expected? What does this line mean? I turned TCP_NODELAY to 0 thinking that it my give me synchronous sockets and that it would remove that error, but it didn't...

Any help appreciated, Thanks
