We are setting up new servers for our client and they are using AX 2012 R3 Retail Online store front. here we have issue with Realtime service where Realtime service pool automatically going down or not reachable. when ever you make Realtime service call from store front then it will not return any results and below error will be recorded in Realtime Service Server.

- <Event xmlns="schemas.microsoft.com/.../event">

- <System>

<Channel>Application</Channel>

<Computer>dtxprodax03.int.deltaco.se</Computer>

</System>

- <EventData>

<Data>Exception occured: [8/1/2018 7:44:30 AM][5246da1c-92ce-409e-9ab5-78ebbe96769a] ValueFactory attempted to access the Value property of this instance.</Data>

</EventData>

</Event>

I don’t see any issues with Realtime service and when you go and check Realtime service then it will be up and running. Again if you recycle or restart Realtime service then again it will start working.

Looking at the error message I don’t see any clue what is causing the issue and when it does down as the error logs only when you call Realtime service from storefront. Till that time no error will be logged in event viewer.

In a day it will go down once or twice remaining all the time it will just working fine.

I have tried changing idle time of application pool to zero but I didn’t see any positive results.

Does anyone come across this issue? it would be great if you share your thoughts on the same.

Many thanks in advance!

Kind Regards

Hi Jayaprakash,

I worked in a similar scenario. RealTimeService (RTS) "freezes". The client had many customizations on the POS and thousands of simultaneous calls do RTS.

Unfortunately we could not find the reason for the problem.

But something that resolved the situation "palliatively" was to change to a "smaller range", Regular Time Intervals Recycling.

IIS > Application Pools > select RTS App Pool > Edit Application Pool > Recycling... > Regular Time Intervals (in minutes) (the default value is 1740)

Another option you can explore to solve the problem would be to change the https to tcp (vice-versa) protocol in RealTime Service Profile I have already seen different behaviors, with different protocols)

or

Set switchValue="Error" to "All" in RST Web.config (perhaps, some more message can help in the investigation)

I Hope this Helps!

Regards,

Rodolfo Recalde.

Hi Rodolfo,

Thank yours suggestions, I have done following changes in IIS and now RTS up and running since 10 days and not went down single time.

1. Idle timeout i have changed it to zero it was 20 min by default for RealTime service application pool

2. Recycling I have unchecked , just to make sure it should not recycle anytime.

Kind Regards
