    > 1. If one of the two containers caused the issue, then the why you needed both of the containers to produce the issue? Why running just the offending one was not enough? Running …

    Comment #14660816

    OP here That's correct, I should have included a chart explicitly measuring the I/O activity done by the two containers, but I can assure you there was literally no I/O activity, a…

    Updated, thanks! I am working with ElasticSearch (ES) more than EL these days and my muscle memory tricked me ;)

    Comment #14659416

    OP here The solution is very simple: as mentioned in the article, just use a newer kernel and always set memory limits for containers, the blog post is based on an older kernel (2.…

    Definitely a feasible approach. Let's just say that the reality has a bit more color and we have some other practical advantages in controlling the exact moment when we disconnect …

    Yes, every commit gets pulled by jenkins which builds the whole thing, runs unit tests and then starts the deployment once the tests pass.

    Both approaches are reasonable (and there's also a third one, ship your application in containers and replace containers instead of instances). We update existing instances because…

    Comment #11590903

    We definitely observed such drops that we attributed to presumably internal ELB scaling activity, but they happen so occasionally that for the moment they haven't been a real issue…

    Comment #11590786

    To be fair, the scenario is less common due to the fact that it happens just when the drained connections are terminated in a certain pattern (as shown in the charts). Still defini…

    Yes, we most definitely can publish a private brew tap. I'm no expert as I mainly use Linux, but my understanding is that I'd need to create a brand new draios/homebrew-sysdig repo…

    We just released 0.1.89 (special release to include the shellshock chisel) a few hours ago, so distribution maintainers aren't that fast: https://github.com/draios/sysdig/releases …

    Yeah, bummer, I can submit a PR to Homebrew but it would take a few hours/days, and we don't ship OSX binaries from Draios, so why don't you go with: https://github.com/draios/sysd…
