Has anyone successfully used ZIP in installation with over 60 devices?


We have several smaller installation with around 20 devices connected to ZIP and they work fine. However, another bigger installation ( around 60 connected devices, mostly secure ) tend to get stuck around once a week. When it happens, ZIP responds to network management commands and client keep receiving events from sensors but none of the devices can be controlled (zware lib returns “no ACK received” error) . Everything is back to normal after ZIP process is restarted. Has anyone experienced something similar? Any advice on how to fix the problem?

We are using latest stable ZIP gateway and the client is based on z-ware library, both Z/IP gateway and client app reside on the same host (local setup)
