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.
