[Samba] Samba 3.0.25b: smbd 99% CPU utilisation with opened MS Word doc

[Ben Tisdall]

Hi I'm trying to upgrade from Samba 3.0.23c on FC4 to 3.0.25b from Samba
sources.

Everything appears to function correctly until an MS word document is
opened from a share - the file opens but the smbd process in question
rockets to 99%+ CPU, stays there & needs kill -9'ing to stop it. This
happens reliably.

I have an appropriate strace & a level 7 log but can't see anything
obviously wrong & would appreciate some guidance as to what to look for.
In the meantime here's my testparm output - this is the same config that
works fine on the previous version.

Thanks!
