The NN will then process the DN's incremental > BR as an initial BR. The NN now thinks the DN has only a few blocks, and > will ignore all subsequent BRs from that DN until out of safemode -- which it > may never do because of all the "missing" blocks on the affected DNs. -- This message is automatically generated by JIRA.
