enabling events show up only on the hour

The resouces we are monitoring for log events are:

- the jbossAS server hosting the rhq server (type JBossAS Server, 
version 4.2.3.GA, monitoring rhq-server-log4j.log)
- the rhq management agent (type RHQ Agent, version 3.0.0.B04, 
monitoring agent.log and command-trace.log
- the linux platform plugin (type Linux, version Linux 
2.6.18-128.1.6.el5.xs5.5.0.50xen, monitoring var/log/messages and 
var/log/secure)

We have seen this issue in all these plugins.
