I'm not aware of any NJE-level keepalive. The time for speculation is past. Gather your evidence and let it speak to you. BE the CSI. What do the network (not host-created) packet traces show at both ends? Are the keepalives going through? If you see TCP RSTs coming in that the other end didn't send, then the game's afoot and the challenge is, then, to locate the offender. For fun, I did a search and saw z/OS APAR PK16058: KEEPALIVE PACKETS NOT ARRIVING AT PARTNER SYSTEM, which tells me it is possible that keepalives are reaching z/OS, but not getting back to z/VM, and z/VM's own keepalive support is terminating the connection.
