[Samba] Got Sighup dumpmg debug info

[Clifford Peet]

I am Running Centos 4.4 on a Poweredge box 2600

Aug 8th 7.30 am, the server had a problem when all the
available disk space had gone, there should of been
180 Gig.
Investigating the logs the last activity was at 04.02
in the morning with this:

************************************************
A reboot was successful and the disk space was back to
normal, I had also notice before reboot that on the
system monitor the /dev/mapper/VolGroup00-logVol00 was
reading 98% and system activity was going crazy.

Since that reboot all system activity has been normal
and seems stable. There was no loss of data.

Looking at the logs again there is still the nmbd
dump_workgroups () message at 4 am, but is this normal
log rotation? or is there a problem with Samba
configuration ?

Thanks to anyone who can help throw some light on
this, I see there has been quite a few question about
this ( nmbd dump_workgroups () messages at 4 am) .
Thanks in advance for any help
