[Knobot-devel] stack overflow

[dbu <db...@us...>]

hello everybody,

with really long documents, i get a stack overflow like the one below.

it does not matter whether there are special characters in it or 
anything. i just wrote "bla bla " and copied it over and over... the 
text is now 138'750 times bla with 1'143 newlines :-)

please do not tell me this is exagerated. we had a document to publish 
with 45'000 characters, which was enough to run into the error.

any idea why this should result into a stack overflow? i found
http://xml.apache.org/xalan-j/faq.html#faq-N102CD (increasing -Xss1m did 
not help) talking about "deeply recursive stylesheet" and now i wonder 
what xslt script the response wrapper actually calls? i mean, there 
should be no need for that much recursion in a simple text with no 
nested elements.
or is there no recursive stylesheet, and this is a bug of xalan?

kind regards,david
