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?

Thanks ur comments.
I'm using tcpdum for debugging issues instead of ngrep.
SER receives a REGISTER message and replys with 483, TOO MANY HOPS
message.
I'm using three alias ('cause I don't know the rigt one to be used):
1.2.3.4, domain.com and sip.domain.com
The diagnostic of X-PRO relates the same as SER.

Look at the ngrep trace on your ser to see what happens (see in
ser/bin/ directory for a filter script with ngrep instructions at the
top). Especially look at what happens when the message leaves your
ser destined for the next hop. (I assume that the first message
reached ser?!)
You may experience this ex. if aliases in your ser.conf have not been
specified for all IP addresses/aliases of your server. Ser will then
not recognize messages.
If the message does not reach ser at all, look at X-Pros
diagnostic log. Post the part related to DNS lookup.
