In addition to BrowserUks diagnosis, my random guess would be that you have a not-so-threadsafe XS component involved, which thrashes some part of memory. Perl recognizes when memory is allocated in one thread and then freed in another thread and does not like that, hence your error message. Maybe, this is caused by some XS component used from more than one thread.

One approach to test this hypothesis would be to rewrite your script so that no modules are used which have an XS component, and to replace all essential parts with pure Perl components. Ideally, this makes the problem go away.

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.
