Got a server edition R9.1.10.0 with a primary, secondary and 3 expansions. Primary is remote to the secondary and the expansions, its all connected through VPLS. Whenever connection is lost to the primary the secondary VM takes over but never gives control back to the primary when they can talk again. So right now SSA shows both VMs active. Problem is both expansions see secondary as the centralized vm server and any DID calls sent to the primary server extensions go straight to VM on the secondary. This is like the 5th time this has happened and the only way I have found to resolve it is a complete system reboot. I ve tried stopping the vm services on both in many different orders with no success, reboot is the only thing I've found that fixes it.
