[AG-TECH] beacon crashes all the time

I think there are too many beacons running for me to get the beacon
client running on my linux box. I always see the following after I
start it up:
Beacon is running with :
localhost = vrvs-ag.internet2.edu
group = 233.2.171.1
port = 56464
ttl = 127
user = beacon
beacon server = beaconserver.accessgrid.org:9997
java.lang.ArrayIndexOutOfBoundsException: 8192
at Report.createReportBuffer(Report.java:253)
at Report.run(Report.java:60)
this seems similar to the problem reported in:
http://www-unix.mcs.anl.gov/web-mail-archive/lists/ag-tech/2000/05/msg00002.html
I tried to change the "final static int maxReportPacketSize = 8192; //
approximately enough for 80 beacons" in the Beacon.java file to 16384 -
but I still get the same message. For my final experiment, I strated
the beacon using the following shell script from nlanr:
#!/bin/sh
#
# Multicast Beacon startup script for non-AG beacons
#
multicast_group=233.4.200.18
multicast_port=10100
beacon_server=dast.nlanr.net
server_port=9999
time_to_live=127
user_name=beacon
# this version runs under Java1.1 and Java1.2
# compile the program using a stable java implementation on your platform
cd /usr/local/ag/apps/beacon_v0.63/beacon
/usr/local/ag/jre1.2.2/bin/java Beacon \
-group $multicast_group \
-port $multicast_port \
-server $beacon_server \
-serverport $server_port \
-ttl $time_to_live \
-name $user_name
it ran forever ... which makes me think I need to find some way to make
the 8192 value in Beacon.java larger ... so how come when I change it to
16384 in Beacon.java it still reports 8192 in the error message? Is
there any hope that I can fix this (without convincing my friends to
quite running their beacons long enough for me to get mine running ...
of course one of them will then be punished ...)
Have I lost my mind?
