very frustrating and will lead to trouble calls. It is incident #00216286 and

<p class=MsoNormal>We would like to inform you of a recent issue we have
discovered, covering the 9.4.1, 10.X series of Desire2Learn, which may result
in diminished performance for your students, faculty and users. The
symptoms are as follows:<o:p></o:p></p>
<p class=MsoListParagraphCxSpFirst style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='font-family:Symbol'><span style='mso-list:Ignore'>·<span

application<o:p></o:p></p>

style='font-family:Symbol'><span style='mso-list:Ignore'>·<span
style='font:7.0pt "Times New Roman"'>
</span></span></span><![endif]>Timeout errors when accessing database items
like quizzes, grades etc…<o:p></o:p></p>
<p class=MsoListParagraphCxSpLast style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='font-family:Symbol'><span style='mso-list:Ignore'>·<span
style='font:7.0pt "Times New Roman"'>
</span></span></span><![endif]>The system will eventually become unusable.<o:p></o:p></p>
<p class=MsoNormal>The issue is due to contention on internal component of SQL
server (tempdb), and all indication is that the cause of delays in the database
are related to the execution of too many queries running. This will cause the
database to become unable to process transactions, making the application
perform poorly.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Desire2Learn recommends these<span lang=EN-CA> updates, they
have been tested and applied to a large percentage of clients in our
datacentres with positive results. Please note the version compatibility below
if you are not a compatible version it will require deployment of the necessary
Service Packs. For additional details please refer to the </span>Database
Performance Monitoring guide on how to monitor and determine if you your
environment is experiencing this issue.<span lang=EN-CA><o:p></o:p></span></p>
