Issue 183969 - This release resolves a race condition between ingest and Garbage Collection (GC) which could cause newly ingested segments to be mistakenly deleted, resulting in data loss and a file system panic.
I just found bug 180010 and from the notes is a duplicate of 183969 which have been addressed on the latest DDOS code.
