The standadrd smb.conf file contains an include
directive for local-smb.conf, which is usually
a file which contains just a comemnt...
I tries touching the smb.conf file and sending a
HUP to the smbd process, (thanks, Jeremy) while
watching it with prstat -p 26111, and the size
headed up to a total size of 29MB and an RSS of 27
over about 80-odd HUPs.
Exiting and restating smbclient created an smbd
with a 29/27MB size, so the problem behavior hasn't
changed.
Comemnting out the printers and repeating the touch/kill
loop caused no increase at all over about 500 touch/HUPs.
There was no effect wit/without the include option.
Looks like a printers issue, whish was a known problem
in the 2.0 timeframe. We had not expected this, as the
previous tests with 2.0.7, on both Solaris and Cobalt,
did not show this growth.
