After upgrading thor environment to hpccsystems-platform-internal-with-plugins_5.6.2-1.el6.x86_64.rpm, resumed work queues from http://10.194.12.2:8010/#/stub/Main. Activity page showed all queues were running - none paused, but jobs on the FCRA thors (thor100_166_fcra, thor100_80_fcra and thor100_84_fcra) were stuck in submitted state with none running. Investigated middleware components and could find no discernable cause. Those queues were paused again on the Activity page and then resumed and, this time, the jobs started running. Error message received: WsSMC.PauseQueue network address not specified. See attached.
