FYI - V12.5.1 Update 1 is now out
Same VLAN problem though
"Trying to load 10,000 policies on a Firebox T10 that also has all subscription services running will probably run the device out of memory."
Ha, ha, ha! Running a T10 with 21 policies and all UTM runs it out of memory enough that upgrading from 12.5 to 12.5 Update 1 took FIVE reboots before catching the magic windows to upgrade without getting a low memory error.
You feel that it needs to be painted red?
