Hey Matt,
Give these two files a try. This version of rastream.c does the record
rejection, and the argus_util.c is needed to make debug message for -d
daemons to go to syslog. So, ……, put rastream.c in ./examples/rastream,
and argus_util.c in ./common. make again, and give it a try.
Should give you something that seems to work, but it may be working
because its throwing data away. Give this a test run, and then, lets
try to fix your issue.

>>>>>>>>>>>>> 4) `/usr/local/bin/rastream.sh` executes `racluster -M replace -r $FILES` against the file /var/opt/argus/Y-m-d/argus_T1. (bad)
