Error: HTTP service “BdcService” too busy

Question

I am trying to access the bdc-service of a sharepoint server via central administration. This is getting me the error:

The HTTP service located at http://[servername]:32843/c023cc02807443888f0bac997c7f5185/BdcService.svc/http is too busy.

I did a lot of google research but could not find a way to get it going.

• I found a corresponding service with the GUID c023cc02807443888f0bac997c7f5185 in site "sharepoint web services" in IIS, but when browsing it, got the 503 error ("service unavailable").
• I restarted the site and it´s application pool ("sharepoint web services root") in IIS, and also the bdc service in the central administration, without success.
• Checked the identity of the application pool and the service account for the bdc-service in central administration: they are the same. Not sure if it is important but had read that in some blog entry.

Answer 1

The application pool of the bdc service had stopped. I incorrectly had assumed that the service uses the pool "sharepoint web services root" while it in fact uses some other pool with a GUID. This pool I also had restarted, but it always stopped becauses the password of the identity user had changed.
