Michael Osipov commented on DOXIA-554:
--------------------------------------
How are we supposed to fix this issue? We can't, since this is a pegdown
problem. I am inclined to close this one as wontfix. You can, of course, create
an issue and PR which migrates the Markdown Doxia Module away from pegdown to
flexmark-java.

> The parsing time for Markdown documents can take very long an hang site
> generation when e.g. long tables are being generated.
> The author of pegdown has marked the pegdown project deprecated since
> 14.12.2016 [pegdown.org /
> https://github.com/sirthias/pegdown/](http://pegdown.org) and advises to
> switch to [flexmark-java] (https://github.com/vsch/flexmark-java).

> pegdown's parsing performance isn't great. In some cases of pathological
> input runtime can even become exponential, which means that the parser either
> appears to "hang" completely or abort processing after a time-out.
> {quote}
> Since the parsing timeout was increased in [DOXIA-498] it is now possible to
> "hang" the site creation with a longer table like the one in this example.
> In case this sample is rendered using version 3.3 of the maven site
