Ubuntu Server 14.04 LTS is the perfect operating system for your budget friendly build. However, there seems to be an issue with many users getting “no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory” whilst in terminal.
This is due to an error with the libpam-smbpass module which synchronizes the system users and passwords with the Samba user database. It can be disabled to remove the memory leak by entering
pam-auth-update
and removing “SMB password synchronization” by unchecking the relevant box
Once the component has been repaired (https://bugzilla.samba.org/show_bug.cgi?id=8449 states that the next release will fix this) you can turn on the synchronization by running ” pam-auth-update” again
