We had a similar after issues migrating from a Solaris 8 2.x Samba
install to CentOS 5 . We had all sorts of timeouts, and weird slowness
and random "read only" messages.
Setting
locking = No
in the globals of smb.conf fixed it.
In our case we suspect it has something to do with locking differences
over NFS between Solaris and CentOS clients accessing a CentOS NFS
server but didn't have time to fully investigate (we were just glad it
got fixed!). If this works for you then maybe there's something more to
investigate...
