* Issues / Comments:
Setup ID #3:
- After working with Anthony Liguori and Steven French we found out why
Samba was not running. I had a cifs unsupported option in smb.conf.
- I kicked off a 96hr run on the Samba setup and the run lasted for
about 14hrs only. Here are the reasons:
** Server Side(Samba) cat /var/log/samba/:
Many messages like the following:
ERROR: string overflow by 3 in safe_strcat
[p0/d0XXXXXXXX/d19XX/d1fXXXXXXXXXXXXXXXX/d146XXXXXX]
** Client Side(fsstress) dmesg:

- This looks like there is a memory leak caused by fsstress.
- I am going to try using another stress test.
* Results:
- Please let me know if you would like to see the results.
