[Christopher Springer]

I'm receiving the following errors in my system logs...

This is on a Samba BDC on a remote subnet (PI-VPN) from the PDC both 
with an LDAP backend.  The LDAP directory is replicated to the remote 
sever via "syncrepl".  Everything appears to be working fine but I'm 
curious what would be causing these errors to occur at random.

Any ideas are greatly appreciated.
