GEN database connection failure messages

Two times in the past week or so, I've seen connection failure messages in ladb and latm log files.  As a result of this, within LID, I cannot access the job scheduler or run a command like count gen user.  It's intermittent.  Today, I finally had to reboot because the connection failure messages were so numerous, and I didn't want to delay our users any more.  The users were starting to notice as well. 

We're on LSF 901 ESP 5, 900 MSP 4 applications on a Windows Server 2003 R2 box.  The app and db servers are separate.  Lawson recommended the following 2 articles


I was wondering if anyone else has experienced this same issue.  If you did, what did you do to fix it?

Other customers with repeated Connection failure messages from SQL Server have used these Microsoft KB articles:
One possible cause is a problem with a newer feature of the SNP that comes with Windows 2003 SP2. The issues that arise from not having updated drivers along with the TCP Chimney feature are documented here: http://support.microsoft.com/kb/942861
Microsoft often recommend rolling back the entire SNP if we see random connectivity issues: http://support.microsoft.com/kb/948496 You may also consider contacting Microsoft support to see if they have any ideas about how to troubleshoot these types of errors.
