[Samba] cannot access files after update samba 3.0.5 -> 3.0.6 (Redhat 6.2)

[Wolfgang Kretzschmar]

Redhat 6.2
kernel 2.2.14-12
Samba 3.0.6
compiled with ./configure --prefix=/usr/local/samba --localstatedir=/var/log/samba --with-lockdir=/var/lock/samba --with-privatedir=/etc/rc-abas.d --with-configdir=/etc/rc-abas.d --enable-debug


I can list directories and write files on a samba share but cannot read files. This happens with Windows XP client or smbclient. After downgrading to 3.0.5 samba works fine again.

It seems to be a Redhat 6.2 problem. On a second computer with Redhat 9 this problem does not occur.

This line is written in log.smbd:

   send_file_readX: sendfile failed for file wk/xx (Das Argument ist ungültig). Terminating

("Das Argument ist ungültig" --> "invalid argument")

and this with debug level 10:

but the file really is not locked by anyone else.

The share is on a local harddisk. This is not a NFS re-export problem.

Looks as if configure thinks that Redhat 6.2 supports some kind of locking but it does not.
