Dave, 

Many Thanks!  It was the same situation you encountered. Once I removed the 
instance setting everything was back to normal.    

Thanks again.

Josh,

Dump your spfile to a pfile and review the contents, checking for 
"job_queue_processes".  I had a situation where I was making a change for all 
instances in the RAC ("sid = '*'") but someone previously had set values per 
instance.  What happens is the instance settings follow the RAC settings and 
being the last ones listed they get chosen.  Dumping to pfile showed me 
something like:

*.job_queue_processes=10
dchdb1.job_queue_processes=6

So although I set the queue to 10 instance 1 would get started with 6.

10g R2
Linux
spfile only, I have deleted in init.ora file to avoid confusion the database is 
open

show parameters  job queue processes 2
alter database set job_queue_processes? scope=both; shutdown abort startup 
nomount show parameter job
job_queue_processes=2

what could be changing the parameter behind the scenes on me. I suspect a bug.
