It filled the disk? Do you have "max log size = 0" set? I
would have expected Samba to rotate the logs. Or do you log
to syslog?

I'll have to look at the code, but this might be the same

As a workaround, you might want to set "kernel change notify = no"

Do you still have the log files around from when this all
started? Without a way to somehow reproduce it, I'd guess
this will be quite difficult to fix.
