Hi all,

Maybe, someone can help me.

I updated the macOS to Sierra and installed the Wowza engine server (v.4.5.0).

The wowza engine server works good, but when I try to open/use engine manager UI then I should wait 30-120 secs per action, sometimes I get error - timeout exception. It is really annoying.

P.S. I didn’t customize configuration the wowza server and I have Sierra v.10.12.1

Hello,

Thanks for contacting Wowza Forums!

From the description, your Mac is saturating resources, causing the Manager to respond slowly.

Can you confirm the following:

- Are you watching the resources while running Manager?

- Confirm your Mac meets the hardware specs listed [HERE](https://www.wowza.com/products/streaming-engine/specifications)

- Confirm you have no other applications running in the background?

- The ports Wowza is using, are they open and not being used by other applications? [Ports](https://www.wowza.com/docs/how-to-get-started-as-a-wowza-streaming-engine-manager-administrator#openPorts)

- Have you read this article on performance tuning? This may help. [Located HERE](https://www.wowza.com/docs/how-to-do-performance-tuning)

Regards,

Jermaine

Hi Jermaine,

I have the same exact problem after installing Wowza 4.6.0 on macOS Sierra 10.12.3. The UI in the browser is extremely sluggish and every action takes very long (20-60 seconds) that makes the UI unusable.

> Are you watching the resources while running Manager?

There is plenty of extra heap allocated to both Manager and Engine. No heap pressure here. Checked the JMX.

> Confirm your Mac meets the hardware specs listed HERE

Sure. No issues here.

> Confirm you have no other applications running in the background?

Confirmed!

> The ports Wowza is using, are they open and not being used by other applications? Ports

None of Wowza ports are in use by other applications.

> Have you read this article on performance tuning? This may help. Located HERE

Yes, but the article is about how to tune Wowza engine with Wowza manager. Currently the manager itself is unusable out of the box.

Any help would be appreciated in order to hopefully get Wowza working during the trial period.

Also checked the logs (both manager and engine) including DEBUG logs. Nothing stands out.

Best,

We are having this same issue. Looking back through this chain this started all the way back in nov of 16’ on the previous version of wowza. And apparently it is still an issue on the newest version. Can we please get some feedback on when this is going to be resolved on this forum. We will submit a support ticket as well, but obviously having been an issue for this long, it may be helpful to make some specific information available as to what’s causing the issue and any potential work arounds.

I’m having the same issue. The Manager hangs at every stage … login, running tests, etc. I’ve tried 4.6.0 and 4.7.0 under Sierra. Sometimes it’ll time out logging in. Sometimes you can get past that, but it will time out if you try to test a stream, display applications, or do anything else with the interface.

Then I tried installing in an El Capitan partition under Parallels. That worked fine. This is clearly an issue with Wowza running under Sierra, and the complaints appear to be going back 6 months.

Hello,

For everyone on this thread, we are continuing to investigate the root cause of these issues.

A partial fix has been posted here, that takes care of some of the Start-up timing issues that some of you may be facing:  
[https://www.wowza.com/docs/how-to-troubleshoot-wowza-streaming-engine-installation#sleep](https://www.wowza.com/docs/how-to-troubleshoot-wowza-streaming-engine-installation#sleep)

For those of you for whom this fix does not alleviate all of the issues, can you post whether or not you are using a MacBookPro with a Touch Bar?

I also want to make sure that all parties on this thread know that for any serious issue please do submit a support ticket here:

[https://www.wowza.com/support/open-ticket](https://www.wowza.com/support/open-ticket)

For any issue that is time sensitive.

Hello,

In working with one of the responders on this thread, it has been discovered that the Slow Manager responses are tied to a permissions error that is possibly created in the update to Sierra on OSx.

Internally we are working on a Known Issues posting that will likely end up being posted here:  
[https://www.wowza.com/docs/important-issues-that-affect-wowza-streaming-engine-software](https://www.wowza.com/docs/important-issues-that-affect-wowza-streaming-engine-software)

After checking a working system’s directories permissions against one showing the issue the following was discovered.

The difference was in /manager/logs/ and /manager/temp/, which had everyone set to rw. (Same for the subdirectories of those two directories). On the malfunctioning install please change the permissions for those two directories to be:

/manager/logs/ system rw wheel r everyone r  
/manager/temp/ system rw wheel r everyone r

… and also applied those permissions changes to the contents of those directories. Started Streaming Engine, started the Manager, saw that it was working properly.

Thanks go out to Ronald for working with our team to discover the underlying issue.

HI, I have the same problem running a fresh copy of your software (Engine Version: 4.7.0.02 build20446) in a Mac OS X Sierra 10.12.5 running on a MacBook Pro 2016 with TouchBar.

My permissions looks to be fine. Is it something regarding with the touch bar?

Hello Benito,

It is unclear if the Touchbar itself is affecting these issues, but in some deep testing with another client their machines with the Touchbar presented the issue while their other devices did not.

It is best if you are still facing issues to submit a support ticket here:

For those still experiencing this issue, I’ve found a fix that worked for me using this answer concerning issues with Java/Sierra on [stackoverflow](https://stackoverflow.com/questions/39636792/jvm-takes-a-long-time-to-resolve-ip-address-for-localhost)

For those to lazy to click the link, run this in your terminal:

```auto
sudo sed -i bak "s^127\.0\.0\.1.*^127.0.0.1 localhost $(hostname)^g" /etc/hosts
sudo sed -i bak "s^::1.*^::1 localhost $(hostname)^g" /etc/hosts
sudo ifconfig en0 down
sudo ifconfig en0 up

```

And you should be back in business.
