      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hello; I tried to send you a private message but it seemed to fail. VMware support is tracking this issue for us also; however since the last time it occured the Sr. Solution Engineer who had been working the issue is now on PTO until July 3. Have you received any additional information as to a fix or workaround to avoid? We were told the issue was likely something related to VDR (vsphere replication).&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks,&lt;/P&gt;&lt;P&gt;John&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Based on the functions reported on the PSOD screen, looks like the issue is in the vSphere Replication stack. You may want to pause the replication in case it is happening too frequently. In the meantime, engage VMware support to get further assistance on this.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Please consider marking this answer as "correct" or "helpful" if you think your questions have been answered.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Cheers,&lt;/P&gt;&lt;P&gt;Supreet&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
