Unable to connect to analyst

Hi all,

When trying to connect to a process from KX Control, the Analyst is not able to open and the error shown in the below screenshot is displayed. The process is running fine and queries can still be successfully run using Java client.

To fix it, I had restarted the KX server. Are there any known root causes for it, and is it possible to recover from this without restarting the KX server?

 

Thanks for sharing @mukhtar
