Hi Harry,

First, FYI, we lost connectivity with thelma for at least 15 minutes
this morning, roughly between 15:25 and 15:40Z.  The networking people
are upgrading our routers and had an oops.

I have not yet tried to run notifyme on a full feed for that long.  I'll
take your advice and run several.  Currently I see on thelma 7
notifyme's to sunny.

Yesterday I wrote Python code to run notifyme, write the output to a
file, and close and start a new log file based on a SIGALRM.  The
SIGALRM comes from a script run by cron, so it could occur at any time. 
I'm nearly finished with a script to grab the signatures from one file
and ensure that each signature appears once and only once in any other
notifyme outputs.  I hope to finish all this today.  Do you have Python? 

Over the past week thelma's queue has held a minimum of 2.6 hours to a
max of 5.6 hours worth of data.

On to your next message...

Anne
