I have a puzzling problem:  a session is apparently waiting on a "cache
buffers chains latch" forever (well, for 40 minutes and counting, so
far); seq# in v$session_wait is static.  "tries" is 0.  

latch free                                                             
address                                                         
C000000004708BC0
number                                                                 
 66
tries  
  0
00
When examining the latch in question (using the address from
v$session_wait.p1raw), I'm not seeing any change in the get, misses,
etc. statistics.  It's as though a process has the latch and won't let
go.  Any ideas from the list as to where I look next?

TIA,

Paul Baumgartel
