Cloud/virtualized cluster node down, with processes blocked in the kernel
Node(s) in my cloud/virtual cluster went down. When I examined system logs on the servers (/var/log/messages), I saw errors like these: Jul 24 13:21:17 ip-x-x-x-x kernel: INFO: task syslogd:1393 blocked for more than 120 seconds. Jul 24 13:21:17 ip-x-x-x-x kernel: INFO: task xfssyncd:942 blocked for more than 120 seconds. Is there a configuration problem with Vertica?
