Just tried several combinations of mod_mono and mono (0.17, 0.18, cvs) The current mod_mono version works just fine with Mono 0.17, but it is segfaulting with Mono 0.18 and mono from CVS. I am looking into it, if anybody figures it out first, please let us know :) Best regards Daniel -- Teach Yourself Apache 2 -- http://apacheworld.org/ty24/
