DW Freeze ups when project include RxJS module

[seroka]

This is a dup of DW Freeze ups when project include RxJS module – Adobe Dreamweaver CC: Feature Ideas

I'm evaluating DW product to a number of users in my organization.

There is show stopper problem where the whole application freezes,
becomes unresponsive, for seconds or even minutes at a time with high CPU utilization.
I've issolated the problem to using the very popular @reactivex/rxjs library that is used
in Angular and many other libraries and frameworks.

I've distilled the problem to a 17 line html file and 29 lines of Javascript to load and lighly use
the RxJS library.

I just downloaded the product, so I highly doubt the issue is based upon any changes I've made to the configuration.

The issue has been seen on
Adobe Dreamweaver CC version 18.1 10155 build
"Standard" mode
on Windows 10 Pro, 64 bit.
10.0.15063 Build 15063
System Manufacturer Dell Inc.
System Model Precision 5520
System Type x64-based PC
System SKU 07BF
Processor Intel(R) Core(TM) i7-7820HQ CPU @ 2.90GHz, 2901 Mhz, 4 Core(s), 8 Logical Processor(s)
Total Physical Memory 31.5 GB
Available Physical Memory 17.6 GB
Total Virtual Memory 36.3 GB
Available Virtual Memory 21.2 GB
Page File Space 4.75 GB

To reproduce the problem.
a) extract the project attached .zip file onto a directory
b) if not already installed, install nodejs and npm
c) run command prompt command "npm install" (this step will gather rxjs and systemjs from the internet)
d) open up the index.html file in Dreamweaver
e) note that the application becomes unresponsive every you switch views for long periods of time. The CPU utilization goes very high during this period.

I don't know much about RxJS and by the looks of the number of replies that you are getting, it may be that you are a loner on this forum.

Having said that, and using the limited amount of logic that I have left (reached saturation point many moons ago), I would suggest that RxJS is not the problem. I say this because RxJS is a JavaScript library similar to

• Google Polymer
• Dojo Toolkit
• jQuery
• midori
• MooTools
• Prototype JavaScript Framework
• etc., etc., etc.

and Dreamweaver has no problem with any of these libraries.

Which leaves us with your mode of installation. With the knowledge that Dreamweaver uses CEP and CEP relies on nodeJS,

• Could it be that there is a conflict somewhere?
• Have you tried using a CDN rather than installing the library locally?
• Have you tried restarting your system after installation?
• Have you had a look at Task Manager to see what is causing high CPU and/or Memory usage?
• Have you had a look at crash reports to find the problem module?

To answer those questions.

Which leaves us with your mode of installation. With the knowledge that Dreamweaver uses CEP and CEP relies on nodeJS,

• Could it be that there is a conflict somewhere?

Maybe.  I don't know anything about CEP.   This is the version

Version of node is

C:\Users\rseroka>node --version

v8.11.0

• Have you tried using a CDN rather than installing the library locally?

If adobe can't reproduce the problem with the 46 line project I provided them, I will take the effort to try this.

• Have you tried restarting your system after installation?

Yes.  No better than before.

• Have you had a look at Task Manager to see what is causing high CPU and/or Memory usage?

Adobe Dreamweaver CC 2018 is the by far highest process by CPU in taskmanager. 

Dreamweaver.exe is the by far highest process by CPU in resource monitor.

• Have you had a look at crash reports to find the problem module?

It's not crashing.  It's just not responsive.

[BenPleysier]

This is my Task Manager

Comparing this to your results and finding the reasons for the differences would be an interesting exercise.

[seroka]

Are there any logs I can pull or other diagnostic tools that would allow you or someone from Adobe determine what is different between your environment an mine?

[BenPleysier]

Maybe Kratika Agarwal​ can help

Do wait for Niharika to get back to you. She is from the Engineering team and can help you.

If you would like to get in touch with the tech support team meanwhile for investigation, please contact us at Contact Customer Care

Thanks,

Thanks.   Does contact customer care create an issue like I did here. https://dreamweaver.uservoice.com/forums/382851-adobe-dreamweaver-bugs/suggestions/34077727-dw-freez...

I've done more investigation.

1.  I loaded on a different PC.  Same results.  

2. With no diagnostics provided, I looked at windows task manager and, related to post from  BenPleysier, there may be a relationship with CEPHtmlEngine.exe.

    

when I click through on Pid 17556, it indicates the process is running normally.

3. I followed the two provided solutions of this dated link . High CPU usage due to CEPHtmlEngine  . 

This did not help either.

This tool looks just like the thing the UX department of 10 is looking to use, but I can't recommend it because it doesn't work for application we want to build. 

At this point, the ball is adobe's court.  I've done leg work to make the problem reproducible and scoured the adobe forums for solutions.
