Hi,
We have tried to upgrade a coupple of FTD's from 6.6.4 to 7.0.1, both 5508-X and Firepower 1010 devices.
We noticed that some of the devices got stucked in a boot loop and we saw the following console output:
Reading from flash...
!!!...Waiting for MIO HB to mature
*** Output from config line 230, "failover"
.Dec 10 09:14:28 demafw1b port-manager: Alert: Ethernet1/8 link changed to UP
ABORT(-87): strcpy_s: source string too long for dest
core0: An internal error occurred. Specifically, a programming assertion was
violated. Copy the error message exactly as it appears, and get the
output of the show version command and the contents of the configuration
file. Then call your technical support representative.
assertion "0" failed: file "constraint.c", line 87
After some research we found the following bug https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx26308
The FTD devices that failed the upgrade had a 33 character long SNMP string and the one that we were able to upgrade didn't.
A TAC case is already opened, but I thought I should give you a warning to first check your SNMP community string if you plan to upgrade to 7.0.1. I am not sure if this bug affect 7.10 as well
