phpdocumentor memory issue

Hi... Just was trying to generate the docs for my pear install... Everything was going fine until I got this error Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 40 bytes) in /usr/share/php/PhpDocumentor/phpDocumentor/phpDocumentorTWordParser.inc on line 269 Normally I wouldn't let PHP use so much memory. And I don't think it's appropriate for it to use so much. Here's the commandline: # phpdoc -t /home/www/web1/html/page/docs -d /usr/share/php/ SuSE 8.1; php 4.3.4RC2 Here's the output of pear list Installed packages: =================== Package Version State Archive_Tar 1.1 stable Benchmark 1.2.1 stable Cache_Lite 1.2 stable Config 1.9 stable Console_Getopt 1.0 stable Crypt_CHAP 0.8.5 alpha Crypt_RC4 1.0.2 stable DB 1.5.0RC2 stable Date 1.3.1beta beta File 1.0.3 stable File_Passwd 0.9.5 beta HTML_CSS 0.3.0 beta HTML_Common 1.2.1 stable HTML_Page 2.0.0RC2 beta HTML_Progress 0.6.2 stable HTML_QuickForm 3.1.1 stable HTML_Select 1.2 beta HTML_Table 1.5 stable HTTP 1.2.1 stable HTTP_Session 0.4 beta LiveUser 0.9 beta Log 1.7.1 stable MDB 1.1.4RC3 devel Mail 1.1.2 stable Mail_Mime 1.2.1 stable Math_Stats 0.9.0beta3 beta Net_POP3 1.2 stable Net_SMTP 1.2.3 stable Net_Socket 1.0.1 stable Numbers_Roman 0.1 stable PEAR 1.3b3 beta PEAR_PackageFileMana 1.0 stable ger PHPUnit 0.6.2 stable PhpDocumentor 1.2.3 stable Translation 1.2.5 stable XML_DTD 0.4.1 alpha XML_Parser 1.0.1 stable XML_RPC 1.0.4 stable XML_Statistics 0.1 beta XML_Tree 2.0b2 beta XML_Util 0.5.1 stable It's not an outrageous number of packages to have installed. Any ideas what may be going wrong? Thanks, Klaus
