The guests are all about 256MB. This is the classic "nothing has changed" story. None of us are aware of anything that has changed over the past few days. Previously, all the guests ran like champs. We did go ahead and reboot one of the troubled guests and that cleared the problem.

How big are the Linux guests? -----Original Message----- We have a handful on Linux guests (20 or so) running in our z/VM 4.4 environment. Yesterday, for some strange reason, 4 of them started having terrible response times. Here are some of the ping times. These were issued from another guest. BAD one: PING pkdl0106.corp.sprint.com (10.185.26.16): 56 data bytes 64 bytes from 10.185.26.16: icmp_seq=0 ttl=255 time=993.377 ms 64 bytes from 10.185.26.16: icmp_seq=1 ttl=255 time=1000.203 ms 64 bytes from 10.185.26.16: icmp_seq=2 ttl=255 time=1000.878 ms 64 bytes from 10.185.26.16: icmp_seq=3 ttl=255 time=1000.145 ms 64 bytes from 10.185.26.16: icmp_seq=4 ttl=255 time=1000.123 ms 64 bytes from 10.185.26.16: icmp_seq=5 ttl=255 time=1000.093 ms 64 bytes from 10.185.26.16: icmp_seq=6 ttl=255 time=1000.155 ms --- pkdl0106.corp.sprint.com ping statistics --- 8 packets transmitted, 7 packets received, 12% packet loss round-trip min/avg/max = 993.377/999.282/1000.878 ms GOOD one: PING pkdl0101.corp.sprint.com (10.185.26.11): 56 data bytes 64 bytes from 10.185.26.11: icmp_seq=0 ttl=255 time=0.885 ms 64 bytes from 10.185.26.11: icmp_seq=1 ttl=255 time=0.127 ms 64 bytes from 10.185.26.11: icmp_seq=2 ttl=255 time=0.111 ms 64 bytes from 10.185.26.11: icmp_seq=3 ttl=255 time=0.157 ms 64 bytes from 10.185.26.11: icmp_seq=4 ttl=255 time=0.184 ms --- pkdl0101.corp.sprint.com ping statistics --- 5 packets transmitted, 5 packets received, 0% packet loss round-trip min/avg/max = 0.111/0.292/0.885 ms Any ideas what to look for? The CPU on all the servers is relatively idle.
