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...
