At an educated guess, you're having problems with oplocks. Samba may
well be granting an oplock on the file, and a local Unix process (i.e.
apache) then gets an error when it tries to access the file.

To fix this, you need to either turn oplocks off on the share, or allow
a Samba granted oplock to be broken by a local Unix process. On linux
2.4 and IRIX, there is kernel support for this.

I would start by setting 'oplocks = no' on that share. This will degrade
performance on the share somewhat, but if it fixes the problem you will
know that it is an oplock issue, and can then try to use kernel oplocks,
assuming the OS on the machine in question supports it.

HTH,

Mike.
