my syetem is FreeBSD 8.2.

i build a memory disk : mdmfs -s 10G -i 512 -o rw md1 /home/test1

After a period of time=A3=ACsome file in the memory disk lose their inode:

#ls
90020595.o

#ls -l 90020595.o
ls: 90020595.o: No such file or directory

it seem the inode of this file was lost.

how to solve this problem?
