Okay, I need further clarification on this error...

Are you referring to rolling the persister log file?  To be clear,
when things are working "normally", this activity is normally logged

=INFO REPORT==== 8-Feb-2009::06:34:23 ===
Rolling persister log to

=INFO REPORT==== 8-Feb-2009::06:39:12 ===
Rolling persister log to

=INFO REPORT==== 8-Feb-2009::06:44:02 ===
Rolling persister log to

... right?

1) Is it "normal" for this activity to occur every 5 minutes?  Is this
a fixed time or is it variable?  If it's variable, what factors
control when and how often this occurs?

2) When one STOMP connection generates this error, does it affect
any/all future STOMP connections?  Meaning, is this error more likely
to occur with 500 connections as opposed to 5?  Or does that not
