Hi Pankaj,
I also faced the same issue. I tried the following.
1, I have open the client in Production.(Changes Allowed, After trying I have reset the original settings)
2, As Deepak said I have changed the parameters in CI and App servers.
3, Run the Update statistics.
4, Reset Buffer.
Finally, issue got resolved.
Kindly try and let us know.
Thanks & Regards,
Arjunprasath Murugesan.
