Until yesterday replication between my two DCs (boa and cobra) was running fine.
Now I am observing one direction boa->cobra being stuck. I noticed this with
a missing update of a DNS entry, but samba-tool drs showrepl confirms?
Output of cobra shows plenty entries like the following (including just he first
of each type):

Reboots didn?t help..
Please advise.
Thanks, Joachim Lindenberg
