As already asked on Stackoverflow:

Please help us help you better by giving us more information:

Is the problem related to writing to a file or does the program also crash when writing to the console?

Can you please update your post and show us a short, but full program that reproduces the problem? Most likely, you can return a large but hardcoded/generated object from ->getFilterObject. Also show us a short but representative template file please.

The best approach likely is to not generate the output as one large template string but to output the information piecemeal. This likely means rewriting your code completely.

If you are generating XML, I recommend XML::Compile for producing XML from a Perl data structure, given an XSD that describes the intended output.

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.
