Monitoring Plugin : Recovering MUC History after an openfire restart

Hello everyone,

Due to a recent Openfire (version 4.2.1) restart, we lost all our MUC conversation history.
They are safe and sound in our MySQL database, but we can’t retrieve the muc history via xmpp protocol. As i understood, the monitoring plugin stores this information in a conversation log (within openfire) these logs are stored later on (following the configuration you set) to the database.
My issue is that the only way to get the messages is through the conversation log, and it seems that these logs are completely flushed after a restart.

Do you know how can i recover these messages or load them into the conversation log?

PS : I am trying to avoid a specific development to query directly the database

thx,
