I have been using Samba 1.9.16p9 on a SCO Openserver 5.02 operationg system. It has worked fairly well of us. However, I discovered that when I transfered a large file to the server (gt. 300MB) all of the available memory would get used up and crash the system. I decided to try the latest version of Samba (1.9.17p1). The memory problem went away but we encountered a new one. Samba would no longer validate logins using our NT server. Instead, it would use the password file on the Unix box. I tried different versions, including alphas, to find out where the login problem got introduced. I found that it started with the "1.9.17alpha1" version. For now, I am using version 1.9.16p11. I no longer have the memory leak or password authentication problem.
