Restrict entry of log into ofPubsubItem table

Hi ,

Every time a messages is handled by openfire, an entry is being made into the DB’s ofPubsubItem table.

This makes the DB to grow bigger and is eating up the Hard Disk space.

Is there any option available, either through configuration or some code snippet, by which i can restrict the entry into the ofPubsubItem table.

Thanks in Advance.

Regards,

Judit
