The mass update feature of SuiteCRM runs for hours on my Bitnami Azure cloud VM, it does complete but runs very slowly. I'm trying to test the scenario in a Bitnami local VM with more RAM. Things generally speed up but the mass update eventually ends with
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
