Thank you all for the replies!

The problem was not in metadb but in the BigBrother monitoring script 
that was accepting good line only the ones containing the following strings 
'flags|ampluo|apluo'.
The fix was to grep out all upper case flags (because the upper case flags
 are negative flags) and keep the only the lower case flags.

The "p", "l" and "o" flags will show only after a reboot but because the data 
replication is working well there is no reason to reboot the server only for that.

Thank you again,
Radu
