Portal for ArcGIS Security 2026 Update 2 Patch

TravisColeHC — Tue, 07 Jul 2026 14:48:36 GMT

I installed Portal for ArcGIS Security 2026 Update 2 Patch last week. I immediately notices a huge spike in error logs as well as CPU and RAM usage on our GIS servers. We eventually tracked down that basically all of our service account permissions has been removed on our ArcGIS Server and Portal servers. It was enough errors to crash ArcGIS Server before we could hunt down the last folders that needed permissions restored.

So just an FYI. We started seeing lots of missing thumbnail errors, Error in checking static data for service: xyzxyzxyz - Service not found Rest. There were some others in there as well causing more severe errors.

We are still monitoring everything to see if the last fix yesterday afternoon fixed it completely.

Hi Travis, just wondering what version of enterprise are you on?

Replying because we just upgraded a standalone ArcGIS Server instance from 11.3 to 11.5 and it started raising hundreds of warnings "Error in checking static data for service: xyzxy - Service not found." In some cases it's raising 15 warnings every minute. These are invariably old services that have been deleted (and verified that none of the server directories have orphaned entries). The thing is, we noticed these before I applied the comparable Server security patches. Wondering if this is a Server-specific issue rather than Portal? I'll create my own post and link in case there is some overlap.
