Rich,

   Yes, I discovered that. I read the Web page on multilog but it doesn't
tell me how to get rid of a zombie instance. What do I need to kill and
restart? It doesn't say.

   However, by stopping postfix and restarting it I lost that multilog access
error mess in the process list. Shrug. The zombie, of course, does no harm,
but the readproctitle access error is still there. Do I do a SIGHUP on that
process ID? Can't hurt, can it?

   It does. I had an ineffective backup (/etc/resolv.conf.staticIP) for
situations like this. Used scp to get the one from the server and that fixed
the problem.

   Interesting. When I'm at the hotels in Corvallis (Hilton Garden Inn or
Salbasgeon Suites), I use dhcpcd to get an IP address that works while I'm
there, but it leaves /etc/resolv.conf alone. This last trip, to the Hood
River Inn, ended up adding a new dns server to the file and leaving the
static, local IP address not working. But, it's fixed now. At least, after
all these years I've learned that such issues are related to dns and to look
at the resolv.conf file. :-)

   Now, about that readproctitle ....

Thanks,

Rich
