in reply to Bad file Descriptor issue in IO::Socket::INET


You don't show any code, so it's hard to tell.

  • Are you properly checking your return values when performing operations that can fail?
  • Are you using global variables to hold your socket handles, possibly overwriting them with other things in other parts of your code?
  • Perhaps you're trying to continue to use a socket handle that closed?


When your only tool is a hammer, all problems look like your thumb.

    Thanks for quick reply.

    I can show the code but it is too long. This script generates service build using perlsvc. It is written in perl. The code I mentioned checks the port checking if this port is active.

      "I can show the code but it is too long."

      Create a short script which purely reproduces the problem you are experiencing. How do I post a question effectively?. Earlier:

      "It was working fine before then I did some changes to it and rebuild this"

      What have you done to determine if the code change introduced this problem? Basic debugging checklist

[Eily]: oh, boolean context uses the "" overload if no bool overload has been defined
[Eily]: (I wondered if overloading bool was actually necessary)
[Corion]: Yeah, you need bool to get a true value, and the rest to return the other value ;)
[choroba]: perl -wE '{package o; use Tie::Scalar; use parent -norequire => "Tie::StdScalar" ;sub FETCH { "x" x int rand 2}} tie my $x, "o" ; say $x for 1 .. 10'
