But in udump directory, I see lots of small trace files, and typically
it has something like

Resized overflow buffer to 9216K (for 8235K LWN)

Resized overflow buffer to 9216K (for 8310K LWN)

*** 2007-09-19 09:02:28.434

Resized overflow buffer to 10240K (for 9352K LWN)

Resized overflow buffer to 9216K (for 8235K LWN)

Resized overflow buffer to 9216K (for 8310K LWN)

 

 

Does anyone know why I am getting these? I am curious what the root
cause is. 

Thanks.
