[Samba] hosting library (ie. PVCS) on Samba

Thanks for the reply.

Indeed, the smbd process is unkillable via kill -9 .
Also, all Samba clients are out-to-lunch at this point.

Here are the last few lines from strace(the file is named 'afile'):
stat64("afile", {st_mode=S_IFREG|0664, st_size=320, ...}) = 0
getxattr("afile", "user.DOSATTRIB", 0xbfffb220, 256) = 4
getxattr("afile", "user.DOSATTRIB", 0xbfffb220, 256) = 4
stat64("afile", {st_mode=S_IFREG|0664, st_size=320, ...}) = 0
getxattr("afile", "system.posix_acl_access", 0xbfffaff0, 132) = -1 ENODATA 
(No data available)
stat64("afile", {st_mode=S_IFREG|0664, st_size=320, ...}) = 0
getxattr("afile", "user.DOSATTRIB", 0xbfffb070, 256) = 4
setxattr("afile", "user.DOSATTRIB", 0xbfffb1c0, 4,

The owner of the file can flip the 'read-only' bit on & off all day.
But, when another user tries it(on or off), I get the aforementioned 
'hang.'

SuSE 9.1 uses reiserfs by default, with EAs & ACLs enabled.
That is what I'm using.

This is the correct fix. When you say it "hangs hard" what exactly do
you mean ? Is it unkillable via kill -9 ? What does strace say ? Sounds
like a kernel EA bug. What filesystem are you using ?
