I am getting a frequent error where my rsync client process just appears to hang. On the client side I will receive several 'SSL_read returned WANT_: retrying/SSL_write returned WANT_: retrying' messages back-to-back
That's a normal part of the SSL protocol. Nothing to worry about.
and then finally the message is always 'Socket closed on read'.
That means your rsync client or server has closed the connection.
Currently in no-blocking mode with the following limits: FD_SETSIZE=1024, file ulimit=2147483647 -> 500 clients allowed
Is there any stunnel bug or system resource limit that could be the problem ??
FD_SETSIZE is a limitation of select(2) function. See the manual for details. New stunnel 4.06 will be able to use poll(2) function instead.
2004.10.11 14:46:32 LOG7[26651:7]: SSL_write returned WANT_: retrying 2004.10.11 14:46:32 LOG7[26651:7]: SSL socket closed on SSL_read
This is strange. Stunnel should not close the SSL connection without sending close_notify message first.
