Re: [MediaWiki-l] InstantCommons - Images disappearing again

In September 2014, I described an intermittent recurrent problem associated with the InstantCommons images. I hadn't seen the problem seen since April or May of 2015. It is now back -- after I upgraded to MediaWiki 1.26.2. Unlike in the past, it hasn't resolved with a server re-boot. I did have record traffic earlier in the week... but the problem --like in the past-- doesn't seem to be traffic related. I cannot find a relation to memory. I'm not running out of memory. The underlying LAMP (Debian Linux Apache MySQL PHP) stack hasn't changed. Product Versions Operating System: Debian (stable) MediaWiki 1.26.2 (f465524) PHP 5.6.13-0+deb8u1 (apache2handler) MySQL 5.5.44-0+deb8u1 The details of what is installed is here: http://librepathology.org/wiki/index.php/Special:Version I do have git installed -- and am using it to upgrade. Like in the past-- the image that is local to the site, i.e. non-InstantCommons, ( http://librepathology.org/wiki/index.php/File:Atypical_ductal_hyperplasia_-… ) is still there-- and displays properly. At the same time, all the images from the InstantCommons are gone. A list of previous posts I did can be found here: https://lists.wikimedia.org/pipermail/mediawiki-l/2014-September/043340.html https://lists.wikimedia.org/pipermail/mediawiki-l/2014-September/043345.html https://lists.wikimedia.org/pipermail/mediawiki-l/2014-September/043348.html https://lists.wikimedia.org/pipermail/mediawiki-l/2014-September/043349.html Help on this would be much appreciated... I have a testing site (pathologyprotocols.org) that is running the exact same set-up (behind a login). It is also failing suddenly in the same way; the InstantCommons images are gone. I wonder whether... - It is the InstantCommons server - There is "talk" between the InstantCommons server and a MediaWiki install (with the InstantCommons activated). I know this as images that are removed from the InstantCommons... are then removed on then MediaWiki install with InstantCommons activated. I think the communication is governed by 'descriptionCacheExpiry' and 'apiThumbCacheExpiry' https://www.mediawiki.org/wiki/Manual:$wgUseInstantCommons ? I wonder whether setting those to infinity would solve anything. - I suspect the thumb cache is purged... and then there is a bug preventing the image from being confirmed as being the same as on the InstantCommons... or there a processing bottle neck as the thumbnails have to be re-created.
