Tvheadend

hi
I am using ubuntu 14.04
after tvheadend process start, it's take about 5 minutes( ! ) until it give me an access to the browser gui or any other access to it (like xbmc)
this is started to happened after I configure my dvb-s to more than one satellite (4-port-switch)
when it was configured to one satellite it was immediate access.
I tried delete .hts directory and reconfigure it but the results are the same.

is this a bug? can I do something to solve it?
thanks.
