dbwr high count of threads

Hi all,

I noticed the dbwr process on Solaris has a very high number of threads
(258).

To me this is not a problem since I am seeing this on my small development box too.
But we recently had some server crash and the consultant is saying Oracle is consuming
a lots of resource, citing the high number of Oracle thread count from the core dump analysis.
I don't believe this lead to the crash because the core stack trace points to NFS calls in both
times.

However, I don't know how to explain the high number thread count mostly from the dbwr process.
Is this normal? I mean, it looks like it's normal since I see this on all of my instances.
How do I convince him that this is ok?

Thanks for your help.

Richard
