Sorry for the spam. Well i was able to fix it, i read the mail list at http://zope.nipltd.com/public/lists/zope-archive.nsf/47ba74c812dbc5dd8025687... and it tell that i can split the file at position 46034131 i do this: split --bytes=46034131 Data.fs cp xaa Data.fs i loose: 3089 bytes, however i don't know this correspond to. and starts zope, and everything goes OK. i make a final test and provide the "-D" option for Zope and everything comes OK, and better because the traceback is printed in the pages that shows an error. I think the problem was made when i install some products from the mk-zprod package. Well i am happy again :) Thanks, Nestor A.
