<div>Hi Carsten,</div>
<div><br>
</div>
<div>Thanks for reply. No idea how this happen but after
increase the shared memory used to run Kamailio , this 500 issue
is gone now. </div>
<div><br>
</div>
<div>BTW, REGISTER being routed seems wrong in my config file ,
therefore after load balancing , client cannot reach each other
by MESSAGE.</div>
<div><br>
</div>
<div>Client --- > Kamailio LB --->Sip01</div>
<div> \ ---->Sip02</div>
<div><br>
</div>
Any idea??</blockquote>
probably register ended on one proxy and the invite/message to it to
the other one. So you have to change the routing logic in the
proxies so that after a failed location lookup, it will send to the
other proxy. There, if its a failure again, reply 404 not found.<br>
<br>
Cheers,<br>
Daniel<br>

Hi,<br>
<br>
i see no point in your config, where the 500 should come
from. It must<br>
come from the servers you are loadbalancing for.<br>
