Apache Bug #28086 (vote for this!): http://nagoya.apache.org/bugzilla/show_bug.cgi?id=28086 PR #64904: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/64904 See also "Bogus" PHP Bug #27735: http://bugs.php.net/bug.php?id=27735 With PHP 4.3.5, the issue was traced to using the bundled version of PCRE (version 4.5). Reverting to the version bundled with PHP 4.3.4 (PCRE 4.3) seems to resolve the problem. To do this, simply replace the ext/pcre directory in PHP 4.3.5 with the one from 4.3.4 and recompile. Alternatively, deselect PCRE from the options menu. Either the bundled version of PCRE 4.5 is buggy or (most likely) it unmasks a bug in Apache. Jon
