[Samba] share of a share and lockups

[ian.harper at vaisala.com]

I am using a linux box with Samba to share up a directory in Read/Write mode
that contains a number of subdirectories, each being an smbmount'd directory
from another machine, these other machines (around 10-12) are running a
variety of SCO Unix and NT 4.0 and NT 2000 with parts of their disks shared
up as read/write.

Until recently it was all working, however when moving to a new server with
RH 7.2 and Samba 2.2.5 it now regularly locks up and no amount of killing of
processes will help and I have to reboot - usually forcing machine to power
off during shutdown because of a hang. 

Has anyone any suggestions/advice ?

Thanks

Ian
