Dear Monks - I recently upgraded to activestate perl 5.16 running on Windows Server 2003 w/ IIS6. A CGI script that has worked for years now errors with "500 Status read failed: A non-blocking socket operation could not be completed immediately.". I wrote a simple test script and the message is coming from LWP::UserAgent. I have tried debugging to no avail. I have written to an activestate forum w/ no reply yet. Is there any known problems with LWP and Perl 5.16? thanks - Dorian dorian@uaqa.com
