Multicast question

With Sp-dense mode configured on various routers connected via ethernet
and hdlc, and auto rp up and runnning.
I can ping the multicast groups that were joined by two rtrs.
However, one of the groups, when I first ping I get a timeout. When I
ping again, I get a response.
After a period of time, I need to ping twice to get a response, the
first seems to time out.
Is this normal activity?
Is the rp losing the entry for that multicast group and goes looking
once it gets the first ping?
No nbma involved, and the rtrs on the cat all have cgmp enabled as does
the cat.
Dense mode works fine....
