I noticed that - since a couple of days - e-mail notifications (enotifs) are sent to me for every change on my watched pages on - http://www.mediawiki.org/ and - http://commons.wikimedia.org/ Enotif is designed to send only a single e-mail notification for the first unseen change and further e-mails are suppressed until I visit that watched page. Perhaps a database problem ?
I increased the severity level, because this function is still misbehaving for an unknown reason, as it currently sends for every change of watched pages (if the user has opted-in to email and email notification). Current version http://www.mediawiki.org/wiki/Special:Version is 1.14alpha
20:31 brion: putting $wgEnotifUseJobQ back for now. change postdates some of the spikes i'm seeing, but it'll be easier to not have to consider it ... 17:38 brion: ~1-hour lag on db3 ...Notifications switched to job queue recently. Since the queue FIFO, it shouldn't cause issues. Slave lag however, can cause problems with wl_notificationtimestamp being stuck as NULL.
Made some tweaks in r46156, r46158. Not sure what the exact issue is here.

I still receive enotifs for each change of a page. Here are recent examples with the relevant mail headers for your analysis. Increased bug priority. *** First enotif: Date: Sun, 25 Jan 2009 19:39:36 GMT Message-Id: <200901251939.n0PJdark032537@localhost.localdomain> the MediaWiki page Project:Developer meet-up 2009 has been changed on 16:57, 25 January 2009 by HardDisk, ... http://www.mediawiki.org/w/index.php?title=Project:Developer_meet-up_2009&diff=0&oldid=234615 *** Second enotif for the same page Date: Sun, 25 Jan 2009 19:39:41 GMT Message-Id: <200901251939.n0PJdfPD032610@localhost.localdomain> ... the MediaWiki page Project:Developer meet-up 2009 has been changed on 19:06, 25 January 2009 by ThomasV, ... http://www.mediawiki.org/w/index.php?title=Project:Developer_meet-up_2009&diff=0&oldid=234676
Nobody synced any code, so it will still be the same :)
(In reply to comment #5) Mail header: Sun, 25 Jan 2009 19:39:36 GMT Page was changed on 16:57, 25 January 2009 by HardDisk, ... *** Second enotif for the same page Mail header: Sun, 25 Jan 2009 19:39:41 GMT Page was changed on 19:06, 25 January 2009 by ThomasV, ... Analysis: Both enotifs were sent at the same minute 19:39, whereas the triggering page changes were committed at 16:57 respectively 19:06 - perhaps this indicates that the wrong databases are used (master/slave) in Enotif, or that the lagging between them needs now to be compensated by redesigning the e-notif software in /includes/UserMailer.php . Perhaps a help to find what has been changed (but should not): Enotif worked without any glitches until first week of January 2009. Sorry, I cannot change software and don't have the necessary skills to understand the master/slave mechanism of the current version, job for Tim or Brion ?
This looks like a dupe of bug 17620, marking it as such. It *may* be caused by bug 10172 as well. *** This bug has been marked as a duplicate of bug 17620 ***
Not a dupe of 17620, but most likely the same as 10172 and thus fixed at the same time.
