James,
I've been testing these rulesets all day. I get about an 80% success rate on
paging. When the breaks occur nothing happens on the nvcorrd log or nvaction
log. I know that nothing is received at the paging server also. The next
time I run my script it may work. A restart of daemons is not necessary.
I hope to install 6.0.2 Monday evening. I know there is a fix for an nvcorrd
core dump problem. I encounter the problem every time I stop actionsvr. Is
there an nvcorrd problem in 6.0.1 that could cause this symptom?
Thanks.

Ray -
netstat -a will show you what I was talking about, which aren't really
queues but messages on the sockets of various UNIX processes. If
everything is working right, you should see the send and receive queues be
at zero or near zero, indicating that the processes involved are getting to
every new message right away.
Since netstat uses the /etc/services file to identify the port owners, you
should see some part of the word "nvcorrd" as part of the named process
owner. If your hostname is too long and you don't get enough displayed,
you can try "netstat -an" which gives a numeric display. nvcorrd's port is
1666. Sockets are assigned in pairs, for interprocess communication, so
you when you have rulesets running you will always see another process
shown who's information is the obverse of nvcorrd's -- the receive and send
amounts will be swapped.
Assuming you are doing paging in the standard fashion, either from an
action node in the a ruleset which calls your own script, or from the pager
icon, both result in the actionsvr actually doing the page. He logs
everything so go check out /usr/OV/log/nvaction.alog and .blog for clues.

Subject: [NV-L] nvcorrd queue
Hello James,
Back in '99 you wrote a nice Ruleset Performance document. In it you talk
about the nvcorrd daemon and the queue (32K) filling up. I'm having a
problem with an intermittent paging ruleset. I was wondering what do look
for in the nvcorrd.?log file to indicate a queue problem.
Thanks in advance.
