The Epicor is down and the following is the error. Anyone know why and please help. Thank you very much.

My first guess would be that the password used for the App (setup in Epicor Admin Console) has changed. Update the password in EAC and re-deploy

99% of the time, I just reboot the Appserver when I get this error and it fixes itself…

1. look at the event viewer on server machine.

2. open this address

@b.huang

http://epi-app01.xxxxx.net/Epicor/Ice/BO/UserFile.svc

in the browser on that server machine.

You will see additional error description

@b.huang

he requested service, ‘net.tcp://epi-app01.xxxxx.net/Epicor/Ice/BO/UserFile.svc’ could not be activated. See the server’s diagnostic trace logs for more information.

Maybe your previous thread will support you on your error.

The requested service, 'net.tcp://sql1/Epicor/Ice/Lib/SessionMod.svc' could not be activated

I usually see this on our dev server if it is running low on memory, as @aidacra suggested recycling will fix it. I have also seen cases where SQL Report Services service will eat up a lot of memory and this service needs to be restarted. Also, it is a good idea in general to put a limit on the max amount of memory SQL can consume.

I suggest rebooting the APP server.

When I see this error, I usually set the WCF throttle in my web.config file using the instructions in the link below:

Multiple "The Requested Service (*.svc) Could Not Be Activated" Errors After Minor Version Upgrade

Hi @LeeB, I wanted to comment that to resolve this issue for us I set the WCF throttle or minFreeMemoryPercentageToActivateService in our web.config file equal to “1” or 1% of memory before it would not allow new service calls. I believe the default is 5% and you can also set this to 0 which means no throttle. Here is where I got the information and suggestion to do this: Since setting this, we have not run into any further “…requested service…blah blah blah…could not be activated…” issues. …

When we saw this message we would also see that 99% of Memory was being consumed on the app server and it was always one of the IIS websites for one of our environments. We would recycle IIS when we would start to see these messages.

[b.huang (Ben Huang)]

Thank you all for your information. Seems like we have app server to SQL server connection issue. Do you guys know what port and protocol used for the connection btw app server and sql server? Thanks.

[ckrusen (Calvin Krusen)]

Can you ping the SQL server from the App server?

[b.huang (Ben Huang)]

Yes, I can ping from app server to sql server.

[ckrusen (Calvin Krusen)]

If you go into EAC, launch the App Server Configuration, go to the Database tab, and Test Connection, do you get an error?

[b.huang (Ben Huang)]

Yes, I tested, it didn’t work

[ckrusen (Calvin Krusen)]

Can you remote into the SQL server and connect to the production DB via SSMS, using the credentials specified in the App Server Config?

[b.huang (Ben Huang)]

Yes, I can rdp and lauch ssms connect to the DB. Thank you very much Calvin.
