Unable to acquire a Read connection

There is a problem with task “Get User Group” in the process . ERROR:An error occurred while evaluating expression: UserGroup:getgroupbyname(pv!UserGroupName) (Expression evaluation error at function 'getgroupbyname': Error evaluating function 'getgroupbyname' : Unable to acquire a Read connection. Safe to retry.) (Data Outputs)

 

-  No process engine lock, No fatal gateway

- No multiple instances at the same time. No heavy load on the engine

-  The process model is run by the designer. No privilege issue.

 

Is that possible when the process is deleting group B, C... from the system, then all other group is get locked until the delete group process completed? 

Is anyone experiences that kind of behavior Group deletion lock all groups.

Thanks

  • Hi Sushik,

    We have faced such kind of issues. In our case it was resolved automatically when server is free to take the request. I think you might already aware of that most of the appian expression rule or function calls are API calls. Sometimes it may happen that the server was bust to take the request that you get this error.

    Just wanted to ask you few queries.
    1) How frequently you get this kind of error?
    2) Is there any specific time frame where you get this kind of error in the day?
