Hello everyone,
I have a Dynamics CRM 365 on-premise environment that is used daily by over 300 individuals.
Sporadically, about once a week, the entire CRM environment will become slow, sluggish, and start throwing errors.
Generally, when this starts to happen, I'll perform a reset on IIS and after about 5 minutes everything will come up and go back to normal for another week or so until it happens again (not at the same time of day or even the same day of the week).
To help provide some more details about this situation, the last time it occurred, I have a WCF Service that creates records in the CRM and it started throwing exceptions over and over again with the following:
System.ServiceModel.CommunicationObjectFaultedException: Microsoft Dynamics CRM has experienced an error. Reference number for administrators or support: #E662A8E9
I then went into the CRM and tried to create an opportunity (unrelated to what the WCF service is doing). The first time I tried to save an opportunity record I received the following error from a plugin that has been running on opportunity create for several years without problems:
The plug-in execution failed because no Sandbox Worker processes are currently available. Please try again.
I then went back and tried to create the opportunity a second time and it worked.
When the system starts 'acting up' I've seen these errors everywhere from account plugins, incident plugins, opportunity plugins, and outside external applications trying to connect to the CRM.
Basically, I was wondering if anyone would have any troubleshooting techniques or tips they would be so kind to offer me in regards to how I can track down what is happening... Maybe something I can run or monitor for example to find the culprit?
Thanks again everyone for all of the help.
