( [id://3333] : superdoc . print w/replies, xml ) Need Help??

If this is a long running perl program then you are probably getting a "MySQL server has gone away" error issue. The DBH will time out after 8 hours (by default). You either do a transparent reconnection or potentially up the timout in /etc/my.cnf. I have seen the PHP guys advocate upping the time out as a fix (bad solution generally) but be aware you will run out of connections unless you close them on exit...

[root@devel3 james]# cat /etc/my.cnf [client] socket=/var/lib/mysql/mysql.sock [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock #set-variable=wait_timeout=3600 <---------- set-variable=max_connections=40 [mysql.server] user=mysql basedir=/var/lib [safe_mysqld] err-log=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid [root@devel3 james]#

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.
