DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following Symantec incidents:

Patch ID: 6.1.0.100

* 3418489 (Tracking ID: 3425878)

SYMPTOM:
I/O's pause periodically resulting in performance degradation. No 
explicit error is seen

DESCRIPTION:
To avoid kernel stack overflow, work consuming a large amount of 
stack space is not done in the context of the original thread.  Instead such 
work items are added to a high priority work queue for processing by a set of 
worker threads. In the case where all worker threads are busy, there is an issue 
where newly queued work may be subjected to an additional delay in processing 
which results in periodic stalls.

RESOLUTION:
High priority work items are processed by a set of dedicated worker 
threads. These dedicated threads do not have an issue when all threads are busy; 
so do not trigger periodic stalls.
