Entry number 250422

This entry is a followup to: 250419

I am paged that online display is empty for run 3837. Check its root 
files, they's corrupted. Possible reason are the replay hasn't finished 
properly or two people is replaying same run.

I tried to replay run # 3837 again. The online plots come back and they 
are consist with golden run.

If same "empty online plots" problem come again, please try:
1. Make sure data checker and shift worker are not replaying same run.
2. Quit analyzer, restart it, and try to do_all() again. (The 
script might ask for whether to overwrite the old root file, 
enter "yes")
