How would any of the above suggestions affect the submission of factors via Aliqueit? Thanks for all the work keeping the db running.

Goodbye, cmd. Last fiddled with by akruppa on 2011-12-27 at 12:44 Reason: a the too many
 2011-12-21, 16:50 #26 EdH     "Ed Hall" Dec 2009 Adirondack Mtns 3×372 Posts Additional primo certificate trouble: I also cannot d/l new numbers to work. Two separate machines that were tested won't open the zips: (first machine) Code: Archive: ../Math/primo/1345/primo_batch_1345.zip [../Math/primo/1345/primo_batch_1345.zip] End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. zipinfo: cannot find zipfile directory in one of ../Math/primo/1345/primo_batch_1345.zip or ../Math/primo/1345/primo_batch_1345.zip.zip, and cannot find ../Math/primo/1345/primo_batch_1345.zip.ZIP, period. and (second machine) Code: 7-Zip (A) [64] 9.20 Copyright (c) 1999-2010 Igor Pavlov 2010-11-18 p7zip Version 9.20 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,2 CPUs) Error: ../Downloads/primo_batch_1345.zip: Can not open file as archive Errors: 1 P.S. I was logged in for the previous trouble with uploading certificates, but not for these downloading attempts. Thanks for all the work you put into keeping the db running.
 2011-12-21, 17:46 #27 henryzz Just call me Henry     "David" Sep 2007 Cambridge (GMT/BST) 3×1,979 Posts I also can't download batches of primo work. Also can I suggest that it might be an idea to increase to automatic proving bound to something higher from 300 once the current backlog is done. Last night I increased it to 380 with maybe an hour's processing. All the original work is done upto past 1300 digits and just needs maintaining. Once I can download input files again I will put some effort in to raising it further.
 2011-12-21, 18:40 #28 wblipp     "William" May 2003 New Haven 23×103 Posts I suspect the massive pointless inputs are being generated mostly through the "Factor Tables" pages. There were a several posts about doing this a few months back, including a comment that it was addictive. If I'm correct, perhaps the impact could be limited by not creating new IDs from these pages - or perhaps limiting these pages to logged in and blockable users.
 2011-12-21, 18:51 #29 wblipp     "William" May 2003 New Haven 23·103 Posts I wonder of the Primo problems may be connected to the large number of PRPs between 300 and 800 digits that showed up when the database returned from downtime? I suspect table checking turned up some problems - perhaps corrupted certificates or perhaps they got overlooked originally.

 2011-12-21, 19:39 #31 Syd     Sep 2008 Krefeld, Germany 2×5×23 Posts Thanks everyone! I just tracked down the error with the certificate files. The disk was filled up with logfiles! I just keep the last week, but that was too much this time. So no space left for zipping/unzipping the files. My intention with this database was to keep it open to everyone, so I´ll go with just a few new id´s per IP created without anything above that: Some little captcha, or: Log in. I´ve already raised the limits for a lot of accounts.
