If recordings are corrupted or incomplete when you view them using the Session Recording Player, you might also see warnings in the Event logs on the Session Recording Server.
Event Source: Citrix Session Recording Storage Manager
Description: Data lost while recording file \<icl file name\>
The issue occurs when MCS or PVS is used to create VDAs with a master image configured and Microsoft Message Queuing (MSMQ) installed. In this condition, the VDAs have the same QMId for MSMQ.
The Session Recording Player might report an internal error with the message - "The file being played has reported that an internal system error (error code: 9) occurred during its original recording. The file can still be played up to the point that the recording error occurred" when playing back a certain recording file.
The issue occurs due to insufficient buffer size on the Session Recording Agent when graphic intensive sessions are recorded.
As a workaround, change HKEY\_LOCAL\_MACHINE\\SOFTWARE\\Citrix\\SmartAuditor\\SmAudBufferSizeMB to higher value data on the Session Recording Agent, and then restart the machine.
