tls shutdown error

[Ken Anderson]

I'm seeing this in the logs. Things are working fine.
Seems to be coming from all mail clients using tls/ssl.
Aug  8 10:48:32 mail user[11588]: popper[28345]: TLS shutdown Error 
[pop_tls_openssl.c:805]

line 805 is this:
------- snip --------
int openssl_shutdown ( pop_tls *pTLS )
{
...
case SSL_ERROR_SYSCALL:
 rslt = -1;
 if ( DEBUGGING || pTLS->m_pPOP->debug )
  log_openssl_err ( pTLS->m_pPOP, HERE, "TLS shutdown Error" );
 break;
...

}
------- snip --------
ideas?

Thanks,
Ken A.
