AEM as a Cloud SDK Dispatcher fails

[tgoodman_mediamonks]

My Dispatcher is failing with the error Function not implemented: AH00023: Couldn't create the proxy mutex 

Looking around, this may be something that can be fixed in the apache2.conf

Is this something I can edit?

Thanks Jörg_Hoh ! 

Just confirming yes - it is the latest Dispatcher SDK - aem-sdk-dispatcher-tools-2.0.81-unix

I am having a problem with it on an M1 ARM Macbook Pro

I have also tried running it on an Intel Macbook Pro, and it works fine.

Ok, this shows that it's a platform issue... Hard to diagnose without having access to an M1-based machine

Please raise a ticket with the support, this should be really handled with priority.

Have a good and healthy 2022!

Looks like a bigger issue, raise it to clientcare@adobe.com

[tgoodman_mediamonks]

Thanks, I have raised it.  Will reply back when I hear more

[Jörg_Hoh]

Are you using the latest dispatcher SDK version? Are you activating a module which is supposed to use mod_proxy? 

(And yes, please reach out to customer care)

[tgoodman_mediamonks]

Thanks Jörg_Hoh ! 

Just confirming yes - it is the latest Dispatcher SDK - aem-sdk-dispatcher-tools-2.0.81-unix

I am having a problem with it on an M1 ARM Macbook Pro

I have also tried running it on an Intel Macbook Pro, and it works fine.

From this research online, it appears that this is a permissions issue.  I could change my http conf to change the mutex settings, which would get around the issue - Is it possible to set those flags in the conf.d settings for AEM as a Cloud?

I also saw this post from someone with a similar setup, but it was an older version, I didn't have the same issue.

The Dispatcher gave a warning about the emulator before I added this to the dispatcher_run.sh environment variables

I also got the mutex error when I ran without this flag

--platform linux/amd64

Also - regarding your question regarding mod proxy  - No

This error occurs running either the default dispatcher src bundled with the SDK or the WKND dispatcher config.

@tgoodman_mediamonks were you able to resolve this issue? I'm facing it as well  

[bartek_887]

Hello @tgoodman_mediamonks 

Do you have any update on that issue? I am facing it for the latest SDK as well. 

[tgoodman_mediamonks · Accepted solution]

Yes - confirmed this is working.  

Using:  Latest SDK AEM SDK for AEM v2022.11.9850.20221116T162329Z-220900 

Also I needed to update Docker with the "Mac with Apple silicon option" here
