Have many stories about The Goblins. For example, Permissions, not working in *particular* folder. I run http://www.xmlsuck.com/ on Squishdot for 1+ year. One day, all of a sudden, 'Search' stopped working. Manage->ControlPanel->pack has fixed it. In fact, it was not *that* simple, because after 'fixing' it that way, Zope has crushed several times next 48 hours, but I was stubborn and now, couple weeks later, everything works fine. I belive that : - everything in Zope depends on ZODB - ZODB is not rock solid So - any day you may start experiencing some funny effects. Not frequently. I would say - once two months, maybe. "ZODB is not rock solid" needs more comment. ZODB has pretty nice self-recovering abilities. In fact, I was *very* happy (and was not expecting) that the 'pack' thing would be able to 'fix' ZODB - from the shape it was. Basically, ZCatalog and everything depending on it was not working (not only xmlsuck part), so I was expecting the damage to be major. I'm making backups, but still ... Something like "Norton Disk Doctor" for Zope may make sense eventually, when/if Zope would gain more marketshare. Perhaps there is some utility out there which is devoted to capturing / fixing inconsistensies in ZODB 'at all costs' ? Some improved version of Manage->ControlPanel->pack ? I tried looking, but found nothing comparable to "Norton Disk Doctor". Rgds.Paul.
