[Samba] tdb_rec_read bad magic in syslog

[James]

Hello,

     I'm receiving the following in my syslog.

Oct 16 15:34:28 pfdc3 samba[1188]: [2014/10/16 15:34:28.182997,  0] 
../source4/rpc_server/drsuapi/getncchanges.c:1646(dcesrv_drsuapi_DsGetNCChanges)

tdb_rec_read bad magic 0xd9fee666 at offset=290196840

What exactly is corrupt and how do I fix it? This is in a multi domain 
controller environment and only appears on one domain controller.
