[Zope] the day of zope headaches

ok, i'm not that superstitious but today must be Zopes equivalent of friday the 13th. i've nothing but headaches with it all day today. maybe the warranty expired ;) here we go the new problem is this: Zope has encountered an error while publishing this resource. IOError Sorry, a Zope error occurred. such a very helpful message. this happened while reindexing the ZCatalog used for the main site search. i do this every week without problems. it takes a bit longer each week but never got this error before. have i maxed it out or something? has anyone else come across this? as always, help greatly appreciated! thanks -<mike>- ps: the catalog is now empty.
