Multiple issues observed where SmartAuditor fails to records sessions, session playback may contain blue background, and loss of recorded session data.

You can confirm the cause of the issue by filtering and reviewing the Windows application event for Source set to "Citrix SmartAuditor Storage Manager" and log events with message set to "Data lost while recording file: <filespec>.icl <number of bytes> bytes missing."

Continuing to identify the issue, filter Windows application event log Event Source MSMQ and Event ID: 2183, and review frequency of the issue. Event ID: 2183 is documented as "Event ID 2183 — Message Queuing System Resources" and includes information for increasing message quota for Message Queuing.

Increase Message Queuing from Computer Management.  After selecting Message Queuing, the Message Queuing Properties dialog box displays. Select General tab, and modify the Storage limits. The default value for Limited message storage (KB) is set to 1GB. Increase the value of Limit message Storage (KB) to a higher value. 

After modifying the value, monitor the application event log, and verify that the events 2183 are no longer logged.

Problem Cause

Smart Auditor depend on MSMQ and may require the MSMQ message storage to be increased in environments where many sessions are recorded.
