[j-nsp] Unstable OSPF

[Nugroho Wahyu Hidayat Adisubrata]

I have problem with MPLS LSP. I'm running RSVP-TE with OSPF as a IGP. my LSP
going unstable, primary LSP switch to secondary LSP for several time. 
I run traceoption in my CORE router then i found that OSPF is unstable and
make RSVP down too. 
I'm very confuse why my OSPF is very unstable. How to make my OSPF stable ?
Any suggestion ?
 
 
 
 
My network is 
PE-----P-----P-----PE
 
PE router is M40e and P router is M320.
My Junos is 7.2R2.4 version
 
 
 
 
Here is my router log:
