I would try to delete and recreate the service. Here is a list of the error codes; Return codes

My best and fastest suggestion would be to use direct connections and NOT the SDE application server.

i have restarted arcsde service many times but, nothing changed

i am trying to understand the reason for something like this but, i couldnt find out if u could guide for getting reason

i have traced sde logs and everything is ok and giomgr is waiting for users and sudden error(-10) is result once user is trying to connect

about direct connection, i have already tried and it is working.

George_Thompson · Answer

If you are using the application server connection (3-tier), I would recommend using direct connection. It looks the ArcSDE application server service stopped working (for some reason) and needs to be restarted on the machine that host the ArcSDE application server.

You may find it difficult to get support for the ArcSDE application server since 10.2.x (last version supported for creating a ArcSDE application server) was retired on July 1, 2019.

Is there a reason that you cannot use direct connections?
