I am not surprised... but I would have to know more about the setup... 
whether ephemeral:y was involved... or partition files or KDE_Gateway. The 
hub TEMS knows a lot of things when there are firewalls involved. When the 
rug gets shaken, a lot of things it knows about start breaking and a 
recycle is needed to cause remote TEMSes and WPAs to re-register and thus 
rebuild the location broker data.

Are Running
Sent by:        [email protected]



Hello All,

I have a strange anomaly occurring when firewall rules are implemented and 
ITM components in different zones go "off-line". I thought the "heart 
beat" mechanisms would allow the rTEMS to reconnect after some sort of 
downtime. The firewall implementation was immediate.

The firewall change to place yesterday evening and when I began to test 
this morning, my rTEMS in one zone was showing "off-line" until I 
restarted the rTEMS again.

Any idea of what occurred and why they didn't check back in "on-line?"

Regards,

Gregory R. Mendes
