Hi David,

this all are debug messages, which are not appropriate to log in a production 
setting. If you get too much messages in your logs, just increase the debug 
level in your configuration.

I'm not an expert with this module, but a quick check in the source code 
reveals that there are two timers run:

* one for updating the DB
* one for expiration old hash table entries

They are both run every the update_period/ update_period - 5 seconds. The 
update_period default is 100s. So normally this timer should not run that 
often. Can you quote the parameter setting in your cfg?

Cheers,

Henning
