Has anyone else noticed this behavior on 2020R2 and later versions?
We are seeing this on a third client environment, and the second time for this particular environ.
On Feb 28th Tenant 3 had a full snap shot taken and restored to Test Tenant 4.
Beginning on the morning or March 3 when a user logged into tenant 4 (or switched from tenant 3 to tenant 4) and this exceeded the 2 concurrent user limit in tenant 4... users logged into tenant 3 were logged out with the message “You have been logged out due to exceeding the number of tenants in the system.”
Restarting the application, via Application Updates SM203510, seems to have resolved the issue and we plan to add this step to our snapshot process for migrating data from PROD to QA/Training environs.
The same thing happened on a Snapshot done on Jan 10, and users logging in throughout the day Jan 11 received this error. Acumatica restarted the server and we had no further issues.
