SSL.pm: untie attempted while 2 inner references still exist

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

My web error log shows an error "SSL.pm: untie attempted while 2 inner references still exist at "cgi:error SSL.pm: untie attempted while 2 inner references still exist at perl5/IO/Socket/SSL.pm"

I do not specifically use this module. So what could have caused cgi error to occur?

Thanks in advance.

You might want to check your web server's access log from around the time of the errors to see what CGI or other perl programs may have been active at the time. If you can identify a source file, you may then be able to add `use strict; use warnings;`, if they are missing, and if it is CGI maybe also `use CGI::Carp;` to further track down the cause of the error messages.

As the maintainer of IO::Socket::SSL I've never seen this message and I have no idea what might have caused this. And there are no information in your question which might help to narrow down the cause of the problem. If you want help in resolving the problem I think you need to strip down what you are doing as much as possible and provide a minimal example which can be used to reliably reproduce the issue.

We need to know (much) more about your program. And, if the message was accompanied by a traceback of called routines, we'd need to see all of that, as well.	[reply]
