DAQ problems with right arm. Couldn't end run 31456 properly. ROC15 timeout.
Rebooted ROC15. After that, runcontrol would not open the data file,
and "Events this run" was always zero. Tried rebooting everything (TS0, ROC1,
ROC15, kcoda, finally rebooted adaql2), to NO AVAIL. Called Bob Michaels, who solved the problem over the phone as follows: kill any processes called et_* (there were none). Remove any files /tmp/et_* (there were none). Type et_start -n 5000 -s 20000 interactively. Check if /tmp/et_sys_onla appears (large file). If so, start rcServer, then runcontrol as usual. Indeed, problem fixed. The mystery remains why et_start does not execute automatically sometimes.
