We have a fairly large IPOSE system with about 1100 endpoints, Equinox, Skype for Business intergration, ACCS, the whole shebang. It has 8GB of RAM and we are currently seeing that the IP Office service is running dangerously low on RAM, with One-X Portal eating more and more (4GB+) until there is nothing left and the service restarts, plus we get a host of alarms in SSA. The IPO Service never fully crashes but it's worrying. Has anyone else seen this?
