        first note, global limit is at 1500, which is why things might be stable.
      • 2015-10-25 29833, 2015

      • ruaok
        should I move to 2000?
      • 2015-10-25 29856, 2015

      • zas
        ruaok: i would first make roobarb behave more like dora, the server is restart far too often imho
      • 2015-10-25 29810, 2015

      • zas
        restarted*
      • 2015-10-25 29829, 2015

      • ruaok
        ok
      • 2015-10-25 29853, 2015

      • ruaok
        I think you have some good points in the email. the server didn't use to start up so slowly.
      • 2015-10-25 29858, 2015

      • zas
        and i think the issue starts when the two servers are restarted within the same time window
      • 2015-10-25 29815, 2015

      • ruaok
        I've been thinking the same.
      • 2015-10-25 29832, 2015

      • ruaok
        another thing that I think we ought to do is to warm up the servers a little.

        ruaok, can you provide any idea of the cost of a week in BCN?
      • 2015-10-25 29842, 2015

      • ruaok
        do at least one search on each of the indexes.
      • 2015-10-25 29812, 2015

        Leftmost: in the context of the summit, metabrainz will pay for nearly everything.
      • 2015-10-25 29834, 2015

      • ruaok
        outside of that you're on your own, save for lodging which is still covered.

        food is likely to be your greatest cost outside of the summit.
      • 2015-10-25 29828, 2015

      • zas
        ruaok: what do you think about the rate limiter thing ? wouldn't be safer to enable it by default instead of relying on this wget remote command ?
      • 2015-10-25 29836, 2015

      • ruaok
        transport is cheap, if you decide to take bus/metro. If you buy a T-10 card, you get 10 trips for 10€.
      • 2015-10-25 29849, 2015

      • ruaok
        zas: yes, let's do that
      • 2015-10-25 29806, 2015

      • ruaok
        Leftmost: a cheap dinner will cost 10€. A nice dinner 20€. Really nice with wine, 30€.

        There was also a pin and two stickers with the logo of the company.
      • 2015-10-25 29848, 2015

      • zas
        ruaok: can we just copy tomcat-8.0.28 dir from dora to roobarb and symlink it ? or there is more to do ?
      • 2015-10-25 29826, 2015

      • ruaok
        or grab the dist of tomcat and unzip it into place
      • 2015-10-25 29842, 2015

      • ruaok
        then jar xf <war file> into webapps/root
      • 2015-10-25 29813, 2015

      • zas
        where is the war file ?

        Thanks, ruaok.
      • 2015-10-25 29801, 2015

      • ruaok
        this is going to be the tricky thing for us -- anyone else who uses that isn't going to want to use the rate limiter.

      • 2015-10-25 29854, 2015

        a chef script for installing would be lovely. :)
      • 2015-10-25 29825, 2015

        yes ... but first i need to understand how it is installed ;)

        those two steps are literally it.

      • 2015-10-25 29828, 2015

        I thought we fixed it a long time ago

        It should just use the submitted file metadata until the data is available via MB's db.

      • alastairp
        set returns True, but if I call get on the exact same input, I only get back about 10% of the stuff I put in
      • 2015-10-25 29816, 2015

      • Gentlecat
        you mean set_multi and get_multi?
      • 2015-10-25 29856, 2015

      • Gentlecat
        because set_multi shouldn't return a boolean
      • 2015-10-25 29807, 2015

      • alastairp
        no, I’m using set individually
      • 2015-10-25 29810, 2015

      • Gentlecat
        it's supposed to be a list of items which failed to be stored
      • 2015-10-25 29812, 2015

      • Gentlecat
        ok
      • 2015-10-25 29828, 2015

      • alastairp
        ok. set_multi returned []
      • 2015-10-25 29816, 2015

        you can try using memcached module directly

        ruaok: in https://github.com/metabrainz/syswiki/blob/master… it is said " the push script on cartman has a 5 minute sleep between pushes, so that the pushed server can recover from its reload before the next server is reloaded."

        I wonder if we should have different monit limits on the two servers.
      • 2015-10-25 29855, 2015

      • ruaok
        that might reduce the chance the they both get restarted by monit near the same time
