I noticed that you have loaded the snmpstats module in your
configuration file. Are you polling SNMPStats with SNMP at all? If
not, it is possible that its interprocess buffer is filling up. The
solution in this case would be to either periodically poll the module,
or disable the module if you aren't using it.
