I have a two-node RAC running = an 11i-ebusiness suite (11.5.9/9.2.0.6 64-bit).  I am seeing the = following from Statspack:

Inst    = Statistic          &nbs= p;            = ;            =           = Total     per Second    per = Trans
-----   = ---------------------------------------- ------------------ = -------------- ------------
1.      = global cache blocks = lost           &nb= sp;           &nbs= p;         = 28            = 0.0          0.0
2.      = global cache blocks = lost           &nb= sp;           &nbs= p;      = 4,410            = 2.7          0.9

We are using three giga-bit = private interconnects going through a switch. This does not see like an = interconnect issue otherwise, I think, I would have seen a higher number = on the 1 node as well.

Any idea what might be causing = it?

Thanks
