I just upgraded to 24.7.8 (I was actually on 24.7.7 and it was working fine... as was it in 24.7.6). I run both my firewalls in Proxmox, so I took a backup snapshot before each upgrade, just in case. When the primary node came back up, the only thing I noticed was that it was pinned up in persistent carp maintenance mode.. I enabled and disabled and the backup failed right over to the primary. Only issue I still have is with Spectrum. For some reason, when I use a vlan on my managed switch (Juniper EX3400 POE), the Spectrum routinely fails to DHCP a new address (I have dhcp snooping and damn near everything else disabled in that vlan that could be interfering). For a goof, I grabbed an old gig switch from Netgear and plugged in the Spectrum primary/backup and circuit.. been fine for 4 months now. Fails over Spectrum with no issues.

Anyway... not seeing the problem in 24.7.8.
