I am running 8 SuSE 2.2.16 instances under zVM V4.2. zVM is connected to the network via a GBit Ethernet OSA connection. The Linuxes are talking to zVM over VCTCs. I am intermittently, a few times an hour, seeing Telnet sessions being disconnected from one or more Linux instances. The users can reconnect after waiting about 30-60 seconds. The output of the VM IND command shows low CPU usage and no paging. The Linux that the user is connected to is also lightly used. Has anyone else ever seen this behavior? Any ideas what to look at? There are no ugly messages in either /var/log/messages or the zVM TCPIP console log.
Thanks, Hank Calzaretta Wallace Computer Services, Inc.
