msg errors chech_log

Hi
i,ve found this error in BBOUT in a debian machine.
this error comes from the check_log monitor

vi /../ BBOUT
shows this errors
bb-local.sh /usr/bin/sort: Warning: "+number" syntax is deprecated,
please use "-k number"

im using the msg monitor (in the server bb-hosts ) and check _log in
the client /ext/
maybe both can´t work together?
how can i diable the msg monitor at the servers bb-hosts??

192.168.x.x         xx.xx.dom            # memory dspace proto iostat cpu2 last

what is the msg monitor? last? proto? dspace?iostat?

thank u very much!!!
