Some discussion/work on the matter at http://bots.wmflabs.org/~wm-bot/logs/%23wikimedia-operations/20150822.txt after [08:14:13] <icinga-wm> PROBLEM - https://phabricator.wikimedia.org on iridium is CRITICAL - Socket timeout after 10 seconds

Dup of T109941 ?

I don't think so...

Merged into T109279. Please reopen that one if it happens again.

Also:

Can Not Connect to MySQL

Unable to connect to MySQL!

Attempt to connect to phuser@m3-master.eqiad.wmnet failed with error #1040: Too many connections.

Make sure Phabricator and MySQL are correctly configured.

The current Phabricator configuration has these values:

mysql.host	"m3-master.eqiad.wmnet"
mysql.port	null
mysql.user	"phuser"
mysql.pass	hidden

To update these 4 value(s), run these command(s) from the command line:

phabricator/ $ ./bin/config set mysql.host value
phabricator/ $ ./bin/config set mysql.port value
phabricator/ $ ./bin/config set mysql.user value
phabricator/ $ ./bin/config set mysql.pass value

I hit this AphrontConnectionQueryException: Attempt to connect to phuser@m3-master.eqiad.wmnet failed with error #2003: Can't connect to MySQL server on 'm3-master.eqiad.wmnet' (99). error a few minutes ago. It seems to be intermittent; refreshing the page a minute or two later worked.

@NiharikaKohli reports in #wikimedia-operations that she's been experiencing this error as well today.

Please reopen T109279, do not use this issue, as it is a duplicate of that one, and problems are centralized there.
