Our server is Windows Server 2003 SP2.
We use Citrix to access all of our Adagio Modules.
This problem has unfortunately been occurring for ~9 months.
The only aspect that I can think of that changed during this period is which Citrix user account we were using in order to pull these reports.
For a period of time, I though this error was occurring only on specific user accounts in Citrix, but have now found that it occurs on multiple Citrix accounts.
Overall, this error only occurs about 25% of the time, and usually only after AR has been open/idling for at least 30min.
Unfortunately, I am not able to provide many more details than these. Any suggestions would be appreciated.
