The text I quoted is from the change log that is published
with each release.
The problem is that that the checks for quota or access permission
errors were not in the right places. The problem is that the error
from rx_Write() did not supersede the error from EndRXAFS_StoreData
and was lost.
The cache manager saw that it had a dirty buffer and continued to
try to write it to the file server.
