Event 1000, Application error ArcSOC.exe

[MichaelJenkins]

I've been trying to troubleshoot some issues on our ArcGIS Server and discovered thousands of entries in the Windows Even log in the Application section that have event code 1000 (you can filter on that),

I'm wondering if this indicating a serious problem or if this is something that looks bad but is actually common and not serious.    We happen to be running ArcGIS Server 10.3.1.   Any ideas?

I'm guessing that this is happening when doing an edit against a feature service?

Event code 1000 is a generic Windows error code for an application crash.  I have seen similar ArcSOC.exe errors in the Windows event log that are unrelate to feature services.
