Asunto: [AG-TECH] AG3 Bridge issue


I've been running a bridge on and off for some time and still run into
the same annoying issue.  After the Bridge process runs for some period of
time and the amount of activity (Quickbridge processes spawned and
goes past a certain point, the Bridge stops functioning properly.  It no
longer identifies itself to the registry and no new entries are added
to the log file.  I've tried different FC5 and FC6 platforms, assuming that
this problem was machine specific, but this behavior has not changed.  I
also tried running Bridge as root, thinking that I was running into some
of restricted buffer limit.  No difference.

The last thing normally logged is some attempts to create new bridges:
04/25/07 14:26:31 -1208707392 Toolkit     Bridge:57 INFO  Bridge request:
mcast 59822
04/25/07 14:26:31 -1208707392 Toolkit     BridgeFactory.py:110 INFO  Method

Allocated port = 50076
04/25/07 14:26:31 -1208707392 Toolkit     BridgeFactory.py:123 INFO  - using
existing bridge

and the BridgeFactory uses an existing bridge.

Then the last item in the log is usually the destruction of all the bridges.
After that the Bridge might as well not be running, because it doesn't show
up in the registry.
The only think to do at this point is to kill and restart the bridge.

Does this sound familiar to anyone?
I'd appreciate any comments or suggestions.
