David,
Thanks for your prompt reply, again.

Well, there you go. The other side sent a signature with the wrong length.
The other side is also OpenSSL. I call SSL_read() there, which does not
return an error. Do you have an idea why is it sending wrong signature
length?
Furthermore, I didn't give you all the information I had.
The protocol errors occurs only when I send a particular message, but
not for every try. For other messages everything works fine.
I've straced the process invoking SSL_write(). Every time I get that
protocol error from SSL_write(), I see that the last write() it invokes
returns -1, with errno set to EAGAIN.
When I send the message and do _not_ get the protocol error, I see that
either: 1) there is no EAGAIN or 2) the last write() sets EAGAIN and
SSL_write() returns SSL_ERROR_WANT_WRITE.
Is the problem on the reading or the writing side? In any case, what can
be the cause of it?
Also, I am using the loopback interface for communication.
Regards,
AK
