Prasenjit Sarkar updated THRIFT-5725:
-------------------------------------
    Description: 
When the Thrift OpenSSL server gets a file descriptor of 0 (which is valid), 
the server stops working and cannot accept new connections because of the 
following code in TSSLSocket.cpp:

 
{code:java}
if (BIO_get_fd(bio, &fdSocket) <= 0)
{ throw TSSLException("BIO_get_fd failed"); }
{code}
 

The fix would be to just change the comparison from <= to <
