Have you experienced this personally? I didn't find any sign of 
scheduled file system checking in the system, that would conflict with 
samba. Hope that corrupt file system itself is not causing this. But 
this is output from debugreiserfs command:

Seems that something is wrong, but don't know how serious is it.
