Hi, When writing recursive xqueries that that manipulate somewhat larger documents, MonetDB frequently quits with the error message !ERROR: interpret: running out of physical stack space! Is there a way to increase the physical stack space? I found no parameter to set in MonetDB.conf, perhaps in the source somewhere?
