Reproduced locally. It crashes pretty quick. I got one crash with the above stack trace, and another one crashing at https://github.com/pingcap/titan/blob/468ddc9727428bf85403a63e6fa3f245d81e6de7/src/blob_format.cc#L171 where state_
equals to kNormal
. Still debugging.

The failure at TestPut
is caused by Titan hitting background error "Column family drop", which is caused by a CF dropped while GC on the CF is still running. Filed #71 to track.

Hit another db_stress failure, which is a db_stress bug and fixed in upstream. The thing is I didn't update titandb_stress to the version in rocksdb 6.4.x. Will make the update.

The file state transit error seems to be caused by file size property collector not being called during flush and compaction sometimes. Still investigating.

titandb_stress pass locally after patching with #72, #76 and #78.
