I asked my colleague, not immediately crashed but the other guy could not connect to OS/390 system right after. it is already set DISCONNECT_TIMEout OFF in the SYSTEM CONFIG file,
but the output of 'Q SET' is "TIMEBOMB IDLE" is it correct? do i need to change TIMBOMB OFF by SET command?

VM always used to start a 15 minute timer when the logon screen encounters a problem: it sets the user in "forced disconnect by system" and when one-one logs it back on withing 15 minutes, it gets "forced logoff by system". Nowadays however you can include DISCONNECT_TIMEout OFF in the SYSTEM CONFIG file (or set the timer to another value than 15 minutes). By the way: LOGON xxxx HERE is not really related: the HERE option allows to log on to the user at the given terminal, even if it still is logged on elsewhere. 2010/4/27 TaeMin Baek <tmb...@kr.ibm.com> Dears, I use z/VM v6.1 and z10 BC. OS/390 V2.10 is running uder z/VM. I logged on z/VM userid to see OS/390 Master Console in IBM personal communication and suddenly my laptop was dead. Unfortunately, OS/390 was crashed and forced by z/VM system at the same time. I think that even though my laptop is dead and session is suddenly closed, it must be still running and can be reconnected by "LOGON USERID HERE" i don't understand why this happened. Is there anybody who has this experience like me and has the way how to protect it not to happen again? or how to detect root cause of it?
