Do you have any tip for resolving these errors? Any kind of suggestion is so impotant.

Server throwing these errors so many times and after some point application server instance as process is alive but node agents accepting application server instance as down, when I look to dmgr it seems like closed. Because of that we are restarting applicatin server instance.

Thanks for your helps...
