[Veritas-bu] bptm logs -- EOM encountered and Automatic cleaning

Good morning

As somebody would have some ideas of the significance of these
messages, such as "send_brm_msg","EOM encountered" or
"TpUnmountWrapper", are they messages an error?
Because, every time this kind of messages appears in the logs, I
receive a syslog error with : " Automatic cleaning of TLD(0) ...."
These syslog and bptm messages appears many times in a day...
 
syslog messages:
