( #3333=superdoc: print w/replies, xml ) Need Help??
The first thought that pops up (which assumes a unix system; if not skip this part) is that you're hitting some sort of resource limit on the system. If you are running this from the command line, check 'limit cputime' in csh/tcsh or 'ulimit -t' in bash/ksh. Also, if the problem is occurring when you log out, you'll need to 'nohup' your program, to prevent it from being sent SIGHUP when you log out.. it's run like 'nohup ./perl_program args'.

If the above doesn't help, there are unfortunately several things that could be causing it outside of perl. As mentioned above, it could be MySQL with the problem. The best advice I can give is to do some verbose debugging in the script: write out to a logfile, check every return code from all system calls and MySQL calls, write success messages for every part that succeeds, etc. Try putting an END block in your perl code to trap the time that it's dying, and see if it's doing so at a regular interval.

Hope this helps.

Use:  <p> text here (a paragraph) </p>

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 or How to display code and escape characters are good places to start.
