John Omernik commented on MESOS-4060:
-------------------------------------
I want to be clear, I am not sure they are actually related to each other; in
my testing, they both showed signs of a memory leak. In some further testing,
it appears that they both seem to have the leak independently of each other.
I.e. if I am just running the Mesos UI without Marathon open, the leak still
occurs. Mesos was the worse culprit of the two, having almost 3x the amount of
memory used than Marathon in the same time period. The only way I believe they
are related is I noticed them at the same time.

> Key: MESOS-4060
> URL: https://issues.apache.org/jira/browse/MESOS-4060
> Project: Mesos
> Issue Type: Bug
> Components: webui
> Affects Versions: 0.25.0
> Environment: All
> Reporter: John Omernik
>
> Basically, in using Firefox, I noticed that over time, my Firefox would get
> to become unusable when I had Marathon and Mesos WebUIs up and running. At
> first, I thought it was a function of my home (Mac) computer and Firefox. But
> when I started a PoC for work, and my Windows install of Firefox had the same
> issues, I started doing more investigation.
> First of all, both at home and at work, my Firefox is only dedicated to
> "cluster" related tasks. Thus, I don't have other tabs that are not Cluster
> UIs.
> My typical setup is to have MapR UI, Mesos UI, Marathon UI, Chronos UI,
> Myriad UI, and Yarn UI all up and running.
> After about 3-4 hours, my browser would get really slow, and non-responsive.
> I'd kill all and start again. Rinse repeat.
> So I did some analysis, and basically found a plugin for Firefox that shows
> on each tab the amount of memory being used. I found that both Marathon and
> Mesos UI were the culprits, and things got really bad after just 2-3 hours.
> With those setup, on Windows, I have the following memory usage:
> MapR UI: 7.7mb
> Myriad UI: 9.8mb
> Yarn: 2.7 mb
> Chronos 10.2 mb
> Marathon: 163 mb
> Mesos UI: 463 mb
> Both Marathon and Mesos continually climb, slowly, up some, down a few, up
> some more, but obviously generally trending up. I guess I wanted to toss it
> out here to see if it's something in my settings, or something that others
> are seeing. It's a problem for me from a usability standpoint, and I am
> guessing that it's one of those things that while not a priority for a
> project, should be looked at.
