Noticed noise from mw1053 in dberror.log: Sun Sep 14 10:07:21 UTC 2014 mw1053 zhwiki Error connecting to 10.64.16.34: Can't create TCP/IP socket (24) Various wikis and DB slave IPs show up. Error 24 is "too many open files". Fairly certain this is a client-side problem as none of the db slaves are anywhere near their ulimits.
