I'm answering to myself. My problems are fixed:
- kernel oplocks = No has fixed the violation error for some
applications. Why the oplocks are refused is unknown, but for now I
don't need them ;
- there is only one application (a CAO drawing tool) for which only
some files causes a violation error, even with kernel oplocks = No.
Looks like there was an interaction with the SAMBA-VSCAN module (version
0.3.6b) somewhere, as disabling this module removed the violation error.
Thanks a lot for your help.
