keyword="detailed" coda problem description
at about 0720, we started to have problems with the left arm daq. the first problem was the trigger supervisor. the TS1 terminal in the "components" page was frozen. we tried ctrl-c. no work. then we tried resetting it from the "Crate Resets" under the hall A general tools. after about a minute, the TS1 terminal in "components" came back alive. we reconnected. Bodo suggested that we kcoda the left arm as well just in case.
we had to kcoda 4x to get it to finally work. each time everything was okay until we started the left arm daq. then right at the beginning of the run, we would have problems with the event builder (EB1). the error message said something about not being able to connect somewhere. the terminal window for EB1 showed segmentation fault. we saw all this 4x before getting the daq to work.
note also that the kcode didn't fix the problem. after seeing the "activate run failed" error once again, we ended the run. we reconnected to EB1 and then pressed "cancel" on the runcontrol. then we downloaded again. finally everything was okay.
i think that this is the order of the events for the coda problems.
