A mainframe operating system is networking software infrastructure that allows a mainframe computer to run programs, connect linked machines, and process complex numerical and data-driven tasks. Modern mainframe design is generally defined by redundant internal engineering, extensive input-output facilities, strict backward compatibility with older software, high hardware and computational utilization rates and high stability and reliability. Well-known operating systems include IBM z/OS, z/VM, zTPF, z/VSE, OS/390, and their predecessors, along with MCP for Unisys ClearPath, and NonStop OS/Guardian on HP/Tandem, and questions regarding the IBM midrange operating system called IBM i, OS/400, and i5/OS.

I have the same problem as described above, after being idle for some time, many sessions of AS400 are being disconnected.
We have also the problem with printers, they connect to AS400 by Print2000 and from time to time they pass into the state "END" as if the connection was broken. It does not happen to each printer at the same time, for me it is very similar to disconnected session - so after some time of being idle.
