Yes. This is a PHP limit on how far to look forward, and loop back, when
searching for matches of regular expressions. PmWiki uses regular
expressions in the markup rules.
You may want to split the very long page into several pages, or the very
long markup block into separate sections/blocks for example with a
single line containing [==] every few hundred lines, or you can increase
the PHP limits.
