rocked crash in 12.1.0 release when ran fio+libfio_objectstore.so

rocked crash in 12.1.0 release when ran fio+libfio_objectstore.so

[攀刘]

Hi Cephers,

When I ran fio_libfio_objectstore.so, I met a crash below after ran 10 mins:

https://drive.google.com/open?id=0B1m1ON51YNOSTFRHRng3YksxRkk

I made three disk partitions：
1) db part, 50GB
2) wal part, 50GB
3) data part, others.

I used all default options of RocksDB.

Could anybody have some opinion?

Thanks
Pan

I haven't seen this one.  Did you exhaust memory?  (Can you reproduce and 
see what the memory utilization looks like?)

Hi Sage，

I ran again for half an hour, this time this crash not be reproduced,
but yes, there is issue about memory：

At the beginning, only small amount of memory were used:
   PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
 32801 root      20   0 1282300 453480 269344 S 196.0  0.3   0:17.99 fio

But after 30 mins, RES went up to 20G, and VIRT went up to 22G ...

Seems memory leak? I will use valgrind to san it.

Thanks
Pan
