[Samba] Internal: Unable to lock /etc/samba/smbpasswd......PROBLEM

On Samba 3.0.5 (and Samba 3.0.6) PDC I typically see messages in the logs of
my Samba PDC of several terminals (I separate logs by the terminal). They
all seem to happen at about the same time and they cause the terminals in
question to get messages indicating that the PDC is not present. After a
few minutes it seems to stop and things resume as normal. I have not had
this problem prior to 3.0.5. I use the smbpasswd and all entries are in the
"NEW" format.
Is there something that I can do to fix this? Or is this a bug in the
current version(s). I had to backoff from Samba 3.0.6 because the problem
was far more disabling to my user community.

Anybody got a workaround on this? Help would be appreciated of course.
I don't see what interrupted system call is being talked about either.
