[06:46:29] jynus: https://phabricator.wikimedia.org/T128737#2250619 I'll purge mysql-server-5.5 (and mysql-server-5.5-core), ok? [06:46:36] yes [06:46:47] I didn't purge to reinstall if it was needed [06:46:58] that actually was worse [06:47:39] I do not provide a profile because on dedicated servers it has a perf impact [06:48:07] the funny thing is that it took a lot of hours to affect the service [06:50:09] jynus: yeah, it's also a dead end since apparmour in jessie (or rather any non-patched kernel) lacks crucial parts of functionality [06:50:27] purged [06:51:05] thanks to you and who discovered it, I may have been puzzled for some hours to understand why it was killed [06:51:53] I will restart the service, we will know soon if it worked [12:18:38] 3 hours later, I do not see a statistical difference in error rate for 10.64.16.144 thread_pool config [14:15:44] I found new had for x1 on codfw, I will clone (again, sorry) to it and put current 2 old hosts as "decommisionable" [14:15:54] s/had/hard/
