Load Generator Failed

Hi,

I am getting the following error when I tried to execute the scenario from LR controller


Error 30937: Failed to create worker thread using driver function.
Error 30804: The transaction server is aborting due to the error: -30937
Error 26612: Communication error: An error occurred while calling the OpenFileMapping function for file name - Session\2\lrchan_sm_mapping_object_lrchan0_3128. (sys error message - The system cannot find the file specified.
Error 10293: Failed to initialize worker thread. Exit with time out - 300


Also the LR VuGen hungs when I tried to replay the recorded script.

Note: My LR components were working properly when I tried earlier.

LR version: 12.02
Comunity Edition

Could you please help me getting this issue resolved.

Thank you.

Regards,
Sathya S
