Rick,

Today we received the error: '2018-07-18 12:00:42.969 - 21_4c1329e7 - Unable to retrieve COM Instance: - /cpwc.wc?' in the wcerrors.txt

Is there any way to configure web connect to send us an email or text message when something like this happens?

We were down until a customer alerted us to it and all it took was a simple unloading of the COM servers and then re-loading the COM servers to fix it but it would be nice to be alerted to it and be on top of it before our customers come to us.

Also, any ideas on what causes an error like this that I can look into?

Thanks,

Scott

No unfortunately not. Errors that occur in the handler are not managed.

I'm not sure why you would get that error unless your COM servers were all hanging. Make sure you have error handling properly enabled you use COM non-interactive mode to ensure that UI errors don't hang your servers.

In the <yourApp>.ini file:

UnattendedComMode=On

Also if you're not already running in .NET mode and using ISAPI, consider using .NET mode which is more reliable and is better able to handle various handler errors.
