Hi Ashley,

Even i think it is problem license expiration. In this case usually EP works fine for sometime, but shuts down after that.

Please check std_server<x>.out file. You will get the exact reason why its happening so.

Also check if the license is proper in VA.

Have you done any changes to hardware recently ??

Best Regards

Raghu.

Hi Ashley,

Once again, have you checked the license ??

If yes and if its proper, then take a backup of the work directory. Create a new one.

Restart EP Instance. Catch the logs at the time of issue. Paste std_server<x>.out.

Not able to recognize what is the exact problem with the current log you have pasted.

Cheers..,
