[Samba] Lots of "Failed to create" error messages after upgrading to 2.0.25c

[Eric Evans]

Hello,

I recently upgraded from Samba 3.0.22 to 3.0.25c on Solaris, and after doing
so I noticed a sudden proliferation of new error messages in the Samba log,
such as:

[2007/08/27 15:36:03, 2] smbd/sesssetup.c:setup_new_vc_session(1200)
  setup_new_vc_session: New VC == 0, if NT4.x compatible we would close all
old resources.

Can anyone tell me what is going on here, and how it can be fixed?

Thanks a lot,
