After a transition to partial mode (not writing frames) and back it was found that h2fw0 was creating corrupt data frames. The transition was made to support LDAS QFS disk reconfiguration.

So data written by h2fw0 and served by h2nds0 in the following time period is corrupt. You should use h2nds1 to serve data in this time period

start:
4/24 22:21UTC 3:22pm local
end:
4/25 17:25UTC 10:25am local

We (CDS and LDAS) are investigating what happened. We will put in checking software to alarm if this happens again.
