Note, no time stamp. /p/astroda/v14_47/bin/dscMurPipe: Got unexpected retval=0 on hdr read. Expected 6 bytes. /p/astroda/v14_47/bin/dscMurPipe: Got unexpected retval=0 on hdr read. Expected 6 bytes. /p/astroda/v14_47/bin/dscMurPipe: Got unexpected retval=0 on hdr read. Expected 6 bytes. Once this started I could no longer take exposures ( spectro in this case, but didn't try imager ). dscRun stop_mursrvr dscRun start_mursrvr Didn't change anything. Still scrolling by in murmur window. Quit all iop/sop sessions. No change. Rebooted host. Big hammer, but certain to clear the problem. It did. Couldn't get to gnats at the time, so PR is only now being filed. No idea what prompted this. Was not even taking exposure at the time it started. Was running apo_plotbias on SoS at the time. sp1> mechSend s spMechVersion v2_5_0 Bootup 719771169 SpectroID 1 SlitID 35 Air On Shutter_open_sensor Off Shutter_closed_sensor On Left_open_sensor Off Left_closed_sensor On Right_open_sensor Off Right_closed_sensor On Coll_motor_A 5513 Coll_motor_B 5529 Coll_motor_C 5514 Requested_exp.time 0.0 Exp_time_left 0.0 Last_exp.time 2.1 Exp_state None Shutter_open_transit .74 Shutter_close_transit .55 Coll_motor_A_status 0x85 Coll_motor_B_status 0x85 Coll_motor_C_status 0x85 sp1> sp2 sp2 sp2> mechSend s spMechVersion v2_5_0 Bootup 719771169 SpectroID 2 SlitID 3 Air On Shutter_open_sensor Off Shutter_closed_sensor On Left_open_sensor Off Left_closed_sensor On Right_open_sensor Off Right_closed_sensor On Coll_motor_A 13649 Coll_motor_B 13653 Coll_motor_C 13658 Requested_exp.time 0.0 Exp_time_left 0.0 Last_exp.time 2.1 Exp_state None Shutter_open_transit .75 Shutter_close_transit .64 Coll_motor_A_status 0x85 Coll_motor_B_status 0x85 Coll_motor_C_status 0x85 im> plotMcpFiducials -mjd 52775 -az -y deg -x fididx -canon -reset -scale -time0 1053094020 -time1 1053096659 -table stdout azimuth scale = 0.014016586180502595 (encoder 1) azimuth scale = 0.014025738978276355 (encoder 2) Encoder2/Encoder1 -
