Do you open your $dbh before you fork? If so, the child may be meddling with it. Have a look at DBI, fork, and clone. for the gory details, but the nutshell version is that any connection open when the fork happens will be owned by two processes. This means that when the child exits, it will disconnect the parent's connection. It also means that if they're both trying to use it for access, they're going to get very confused.

A simple way to handle this is not to have a connection open during the fork.

The other way to handle it is to have the child set $dbh->{InactiveDestroy} = 1 and then undef the $dbh.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
