[Serusers] DNS

Well, trying to think in straight lines here:
1. Too many hops should be sent as a result of the following line in your ser.cfg:
if (!mf_process_maxfwd_header("10"))
2. So, we have one of two possibilitites:
a) The test triggers when it should not
b) The test is correct
3. b) is very likely (unless you have a config error), so we have the following possibilities:
i) The header has currectly recorded too many hops when it reaches ser
ii) The Max-Forwards header is set to too low in the INVITE
iii) ser forwards the INVITE to itself over and over until too many hops is reached
Have I missed anything? Maybe you could post the tcpdump and xpro logs?
