    OpenSSL freeze TCP/IP out


    I have a Mercury site at home with this configuration from About dialog. Runs in Windows 7 Professional SP1 64 bits in Spanish.


    Mercury/32 version: Mercury/32, v4.80.149, Aug 18 2015

    Operating mode: Standalone

    Windows version: 6.1

    MERCURY.EXE directory: C:\MERCURY

    Base directory: C:\MERCURY

    New mailbox location: C:\MERCURY\MAIL\~N

    TMP environment variable: C:\Temp\angel

    TEMP environment variable: C:\Temp\angel

    [No license installed]

    All works fine but from time to time, the TCP/IP protocol is blocked outgoing. I can't browser any web page, all browsers fails: IExplorer, Firefox and Maxthon. But there are incoming connections: web server Apache, FTP server, etc. The solution is reboot computer.

    I revised all programs use TCP/IP heavily and I found this in Mercury. The module MercuryD (POP3 client) polls mails each 5 minutes from several servers and accounts (telefonica, gmail, yahoo, etc). As you can see in the log session, first this Warning: SSL connection improperly closed by remote host. In the next poll, this error OpenSSL timed out during handshake. After that, the TCP/IP protocol blocks outgoing communications. Any ideas what it happens. Don't hesitate to request more info. 

    Thanks a lot. Angel.
