Re: [Knobot-devel] stack overflow

[<re...@gm...>]

hi david,

since version 0.2.7 knobot comes with a custom build of xalan patched to
avoid a memory-leak situation with the symptom you describe. Starting
KnoBot the normal way, set's the endorsed-lib system property so that
the shipped version of xalan is used. Since august 2005 however, a new
version of xalan might have been released, so it might be worth checking
it out.

cheers,
reto
