Information post rather than a question/ problem.
We had suffered for some time with poor DHCP service at remote site when we lose Internet connection to our main site and all traffic fails over to the remote link.
It does appear to be fixed by FW upgrade to (in our case) 6.2.7.2
It was always difficult to keep up with FW releases especially on the smaller site with a single core in constant use.
The release notes do hint at some DHCP issues and in this case only seemed to be apparent when taking the load from both sites.
Just wanted to share as it caught us out at the times when we needed the switch to justify its cost.
