[j-nsp] isis adjacencies and isis database entries

On r1, r2 is in list of "show isis adjacency". with the help of traceoptions under "protocols isis" (r1), I can see LSPs (other routers) coming via the interface (connecting to r2). Obviously r2 is advertising LSPs via this link.

Yes, traffic flows between the two interfaces (connecting r1 and r2) in both directions.

BTW, the interfaces are Gigabit Ethernet type, but operating in ptp mode.

but in some cases, they are not. I have one router (say r1), it has adjacency with r2 (on the output of "show isis adjacency) but the r2 entry doesn't show up in the output of "show isis database details". 
Hmmmm.... is R2 advertising anything?

also the interfaces are taking traffic between r1 and r2. Why is that? 
Can you clarify... are you talking about traffic to the adjacent interface on R2 or something else like a loopback?
