samba - Feb 2014 - Samba 3.6.22 corrupting filesystem on AIX

Hi,


I have compiled then installed Samba 3.6.22 on my AIX 5.2.

When I start SMBD it systematicaly corrupts the filesystem on which it 
is installed and fails to start

I start SMBD on an other port because an old samba (2.2.8) is already 
running and I have to validate 3.6.22 before shuting down the old one.

You'll see more informations bellow :
- smbd output
- IBM errpt corruption report

Does anyone have an idea about this ?

the SMBD output ( "Invalid file system control data detected" 
corresponds to the filesystem corruption ):

  175 ) LIBPATH=/i/infext/samba-3.6.22/lib/ ./smbd -i -S --port=13900,44500 -d 1
--configfile /usr/local/samba/lib/smb.conf
smbd version 3.6.22 started.

I would suggest it is the opposite.  Your file system is corrupt, and
Samba is encountering that corruption when attempting to enlarge a TDB.

Samba is a user-space application, if it can corrupt your file system or
crash your kernel, then it is a kernel bug, not a Samba issue.

Samba is regularly used on AIX, so I strongly suspect this is a
system-specific issue, and I would take every measure to secure the data
on your server before the corruption claims something even more
important.

Also, do confirm this isn't something silly like just being out of disk
space.
