gap in postgresql metrics - have to restart agent

Hi!

Does anyone suffer the problem, that the agent somehow looses the connection to the postgres server? Metrics are OK for a while, but after a certain abount of time, the agent stops measuring the process data.

Database data is queried fine, but there's no process dtaa at all.

It cannot be (I guess) because of the postgres version (9.2) isn't supported by the plugin, since there would be no measurement at all, if this was the problem! Furthermore there's another postgres server on another host running the very same version of RHQ agent, and there's the same problem, but with different dates when the measurement went wrong.

What can I do to help framing the problem? Any logs, or screenshots, or whatever...
